Final answer:
The slack time for each activity in Roger Ginde's supply chain management certification program development can be calculated by subtracting the duration of the activity from the total available delivery time.
Step-by-step explanation:
The slack time for each of the activities in Roger Ginde's supply chain management certification program development can be calculated by subtracting the duration of the activity from the total available time for delivery. In this case, the delivery time is from 10 a.m. to 2 p.m., which is 4 hours.
For example, if an activity takes 2 hours to complete, the slack time would be 4 hours - 2 hours = 2 hours. This means there is 2 hours of buffer time available before the delivery time window ends.
Each activity will have a different duration, so you need to calculate the slack time for each one using the same formula.
