Urgent math needed asap look at the attached photo. the graphic shows a schedule network diagram for a 1967 corvette restoration project. what is the duration of the critical path? question 4 options: 12 days 27 days 29 days 30 days

Fourth option: 30 days

Step-by-step explanation:

We three path to complete the project:

Path A:

A1 → A2 → A3

10 days → 8 days → 9 days = 27 days

Path B:

B1 → B2 → B3

2 days → 7 days → 3 days = 12 days

Path C:

C1 → C2 → C3

10 days → 8 days → 12 days = 30 days

Then the duration of the critical path is 30 days, we can't conclude the project until each path has finished

you probably already have the answer but anyways it's b. 15.0
