A bottling machine has a theoretical capacity of 100 bottles per minute. During every ten hour shift it operates continuously but is shut down once for 30 minutes for cleaning, inspection, and lubrication. What is its rated capacity?
A)100 bottles/minute
B)95 bottles/minute
C)90 bottles/minute
D)85 bottles/minute

Question

Quizplus · Accepted Answer

The machine operates continuously for 10 hours, which is equal to 600 minutes. During this time, it is shut down once for 30 minutes, so the actual operating time is 570 minutes.

The rated capacity is the maximum output that can be achieved with ideal conditions. In this case, the theoretical capacity is 100 bottles per minute, but because the machine is shut down for 30 minutes, the actual production time is reduced.

So, the rated capacity is calculated as:
Rated capacity = (actual operating time / total operating time) x theoretical capacity
Rated capacity = (570 / 600) x 100
Rated capacity = 95 bottles/minute

Therefore, the best choice is B.
