Question 1

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion, operation and maintenance. The total traffic t is used to determine the cost of 5t² + 7t. What is the marginal cost?

Accepted Answer

To find the marginal cost, we need to take the derivative of the cost function with respect to traffic t.

The cost function is given as 5t² + 7t.

Taking the derivative with respect to t:

dC/dt = 10t + 7

Therefore, the marginal cost is 10t + 7.

Hence, the correct choice is D.

Question 2

Which mode of transportation is the most expensive?

Accepted Answer

Air transportation is the most expensive mode of transportation as it is the fastest and most convenient way to transport goods and people across long distances. It requires specialized infrastructure and high fuel costs, making it more expensive than other modes of transportation such as water, rail or truck.

Question 3

The ________ is the party that moves or transports the product.

Accepted Answer

Carrier is the correct choice as they are responsible for moving or transporting the product from one place to another. The producer creates the product, the shipper prepares the product for transport, and the consumer receives and uses the product.

Question 4

________ are the preferred mode of transport for online businesses such as Amazon.com and Dell, as well as for companies such as W.W. Grainger and McMaster-Carr that send small packages to customers.

Accepted Answer

Package carriers such as UPS, FedEx, and DHL are the preferred mode of transport for online businesses and companies that send small packages to customers. They offer efficient and reliable delivery services with tracking and insurance options for the packages being shipped.

Question 5

Which mode of transportation is the least expensive?

Accepted Answer

Water transportation is considered to be the least expensive mode of transportation as it has the lowest fuel consumption and is capable of handling large quantities of goods at a time. It is also environmentally friendly, with lower carbon emissions compared to other modes of transportation. However, it may not be the fastest mode of transportation and may have limited accessibility depending on the location of the port.

Question 6

The ________ is the party that requires the movement of the product between two points in the supply chain.

Accepted Answer

The shipper is the party responsible for moving the product between two points in the supply chain. They are the ones who contract with the carrier to transport the product. The producer is the one who creates or manufactures the product, the carrier is the one who physically transports the product, and the consumer is the one who ultimately purchases and uses the product.

Question 7

Which of the following is the fastest delivery method of transportation?

Accepted Answer

Air transportation is the fastest delivery method as it can cover long distances within a short period of time. It is used for delivering goods that need to be delivered urgently or have a short shelf life. However, air transportation is also the most expensive method of transportation.

Question 8

In almost all countries, roads, seaports, airports, rail and canals have this in common.

Accepted Answer

Roads, seaports, airports, rail and canals are considered part of a country's infrastructure, and the vast majority of such infrastructure is built and/or managed by the government rather than private entities.

Question 9

Which mode of transportation is the dominant form of freight transportation?

Accepted Answer

Trucking is the dominant form of freight transportation due to its flexibility, extensive network, and ability to deliver goods directly to various locations.

Question 10

Transportation plays a key role in every supply chain because

Accepted Answer

Transportation is necessary in every supply chain because products are rarely produced and consumed in the same location. The cost of transportation can have a significant impact on the profitability of the supply chain, and therefore it is important to carefully consider transportation options and optimize logistics to reduce these costs.

Question 11

The key players in any transportation that takes place within a supply chain are

Accepted Answer

The carrier is the entity responsible for physically transporting the goods from the shipper to the receiver. While the other options may also be involved in a supply chain, the carrier is the essential player in transportation.

Question 12

Which mode of transportation is used primarily for petroleum and natural gas?

Accepted Answer

Pipelines are the most common mode of transportation for petroleum and natural gas due to their efficiency and cost-effectiveness in transporting large quantities of products over long distances.

Question 13

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion, operation and maintenance. The total traffic t is used to determine the cost of 5t² + 7t. What is the average cost per motorist?

Accepted Answer

The average cost per motorist is found by dividing the total cost by the total traffic, t. The total cost is 5t² + 7t, so the average cost per motorist is (5t² + 7t) / t = 5t + 7.

Question 14

Investment decisions regarding the transportation infrastructure (rails, locomotives, trucks, airplanes, etc.) are the primary concern of

Accepted Answer

Investment decisions regarding transportation infrastructure are primarily the concern of the carrier, as they are the ones responsible for transporting goods and ensuring efficient logistics. Shippers, suppliers, and manufacturers may have input or preferences, but the carrier is ultimately responsible for the decisions and investment in transportation infrastructure.

Question 15

________ carriers offer a very fast and fairly expensive mode of transportation for cargo.

Accepted Answer

Air carriers are known for their fast delivery times and their ability to quickly move cargo across long distances. However, the cost of air transportation tends to be higher than any other mode of transportation.

Question 16

Which of the following uses transportation to minimize the total cost (transportation, inventory, information, and facility) while providing an appropriate level of responsiveness to the customer?

Accepted Answer

The shipper is responsible for arranging transportation of goods and minimizing the total cost while meeting customer demands. They also manage inventory levels and ensure timely delivery to customers, making them the best choice for this scenario. The supplier supplies the goods, the manufacturer produces them, and the carrier is responsible for physically transporting them.

Question 17

The movement of product from one location to another as it makes its way from the beginning of a supply chain to the customer's hands is referred to as

Accepted Answer

The answer of The movement of product from one location...

Question 18

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion, operation and maintenance. The total traffic t is used to determine the cost of 5t². What is the average cost per motorist?

Accepted Answer

The cost of using the highway for one motorist is given by:
(cost for total traffic t) / (total number of motorists)
= (5t²) / t  [since we are considering one motorist, t = 1]
= 5t
Therefore, the average cost per motorist is 5t.

Question 19

Suppose that a highway is governed by a use fee charged to motorists that is based on congestion, operation and maintenance. The total traffic t is used to determine the cost of 5t². What is the marginal cost?

Accepted Answer

Marginal cost is the derivative of the total cost function with respect to the level of traffic t. Therefore, the derivative of 5t² with respect to t is 10t. So the marginal cost is 10t.

Question 20

________ typically move commodities over large distances at lower costs per unit shipped.

Accepted Answer

Rail transportation is known for its ability to move large volumes of goods over long distances at a low cost per unit shipped. This is because railways have higher carrying capacities and require less fuel than other modes of transportation such as air or truck.
