Answer 1

Answer:

.a. Number of hours: 106

b. Which jobs can be delayed without delaying the early start of any subsequent activity?

b and d

Explanation:

28 20 20 20 Paths ahd h 2 1t10t 2 8 t 2s t S =64 h 1 + 10 +20 t40+ 20t s 96 1 20 t 2 8 +20+ S 74 a-ce - h 20t 20+4012st5 -106

There are totally 4 paths possible. The path with the route a -> c -> e -> f -> g -> h

= 1+20+20+40+20+5

=106

The path with b and d has slack, so the activity can be delayed.

b has the slack of 20-10 = 10

d has the slack of 80-28

= 52.
