QRS Corp. is designing a product layout for a new product. They plan to use this production line 10 hours a day in order to meet forecasted demand of 900 units per day. The following table describes the tasks necessary to produce this product: $$\begin{array} { l l l }
\text { Task } & \text { Time (secs) } & \text { Immediate Predecessor } \
\hline \text { a } & 34 & \text { none } \
\text { b } & 20 & \text { a } \
\text { c } & 10 & \text { b } \
\text { d } & 16 & \text { b } \
\text { e } & 10 & \text { c } \
\text { f } & 24 & \text { d, e } \
\text { g } & 38 & \text { f }
\end{array}$$ For output to equal forecasted demand, what should be the actual cycle time for this production?
A) 32 seconds
B) 38 seconds
C) 40 seconds
D) 76 seconds
E) 152 seconds

To calculate the actual cycle time, we need to add up the times for all the tasks and divide by the desired output per day, which is 900 units.

Total time = 34 + 20 + 10 + 16 + 10 + 24 + 38 = 152 seconds

Actual cycle time = Total time / daily output = 152 / 900 = 0.1689 hours

Convert hours to minutes and then to seconds:

0.1689 hours = 10.134 minutes = 608 seconds

Round up to the nearest multiple of the longest task time, which is 38 seconds:

Actual cycle time = 608 seconds rounded up to the nearest multiple of 38 seconds = 40 seconds.

Therefore, the best choice is C.
