Question

Quizplus · Accepted Answer

Both activities have 4 hours of slack time, which means they can be delayed by up to 4 hours without delaying the project completion time. However, if they are delayed by 3 hours each, the total delay is 6 hours (3 hours for activity C and 3 hours for activity G). This means that the minimum project completion time will be delayed by 6 hours, which is the answer choice B.

Activity C Is an Immediate Predecessor of Activity G
