Quizplus · Accepted Answer

The average completion time is calculated by summing the completion times of all jobs and dividing by the number of jobs. The completion times for the jobs in the order they arrived (V, W, X, Y, Z) are 3, 4, 8, 10, and 15 hours respectively. The sum is 40 hours, and dividing by 5 jobs gives an average completion time of 8 hours.
