Examine the figure given below.

In this project network diagram, what is the total float for Activity I?

A.
Three

B.
Zero

C.
Five

D.
One

Explanation:
The float for Activity I is three days. The early start for Activity I is Day 17 and the late start for
Activity I is Day 20. Therefore, the difference of the early start and the late start reveals the float as
three days. It is possible, and acceptable, to use the difference of the early finish and the late
finish to find the float, as the value will be the same amount.
Answer options B, D, and C are incorrect. These are not the valid calculation for the total float.
