A worker is assigned three tasks,A,B,and C,each having a duration of 10 days.One approach to completing these tasks would be to focus on one at a time,complete it,and then move to the second,followed by the third.One multitasking approach would call for dividing each task in half and rotating from one to the other so that the first halves of A,B,and C are completed before the second halves of A,B,and C are completed (always in this order).What is the difference in the average completion times for the multitasked activities when compared to the one at a time approach?
A)The multitasked activities take 5 days longer.
B)There is no difference in completion times for the two approaches.
C)The multitasked activities take 5 days less.
D)The multitasked activities take half the time.

For the one at a time approach, each task would take 10 days to complete, resulting in a total of 30 days for all three tasks. 
For the multitasking approach, the first halves of all three tasks would be completed in 5 days, and then the second halves would be completed in another 5 days. This would result in a total of 10 days for each of the three tasks, or a total of 30 days for all three tasks. 
Thus, the multitasking approach takes 5 days longer on average than the one at a time approach.
