Quizplus · Accepted Answer

To calculate the number of customers waiting in line, we need to use Little's Law, which states that the average number of customers in a queue is equal to the average arrival rate multiplied by the average time in the queue.

Average arrival rate = 120 customers per hour = 2 customers per minute

Average time in the queue = 5 minutes (since each customer takes about 5 minutes to complete their transaction)

Therefore, the average number of customers waiting in line = 2 x 5 = 10

So the best choice is (D) 10 customers.
