all possible paths :

A-B-D-G = 3 days + 4 days + 6days + 6 days = 19 days

A-B-E-H = 3 days + 4 days + 4days + 8 days = 19 days

A-C-F-H = 3 days + 6 days + 4 days + 8 days = 21 days

critical path : A-C-F-H = 3 days + 6 days + 4 days + 8 days = 21 days

critical path is a longest path among all possible paths which has longest time to complete the project..

project completion time = critical path time = longest time to complete a project = 21 days
