A) 162 
B) 72 
C) 54 
D) 30 
E) 6

Quizplus · Accepted Answer

The minimum possible cycle time can be calculated by adding the duration of all tasks and dividing it by the number of work hours in seconds. 
Cycle Time = (Task 1 + Task 2 + Task 3 + Task 4 + Task 5)/Number of work hours in seconds 
Cycle Time = (0.8 + 0.9 + 0.7 + 1.1 + 0.6)/8 x 60 x 60 
Cycle Time =  0.9 seconds (rounded to one decimal place)

Therefore, the minimum possible cycle time is 0.9 seconds, which is closest to option C) 54.
