An activity has an optimistic time estimate of 25 days, a most likely estimate of 29 days, and a pessimistic estimate of 34 days. What is the expected duration of the activity

The expected duration of the activity is 29 days and 4 hours.

Step-by-step explanation:

Step 1:

The optimistic time, = 25 days,

The most likely estimate, = 29 days.

The pessimistic time, = 34 days.

According to PERT, the expected duration of the activity,

Step 2:

By substituting the given values, we get

0.1666 days =

29.1666 days approximately equal 29 days and 4 hours.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
