Question

Quizplus · Accepted Answer

The average job flow time is the total time taken by all jobs in the sequence, including waiting time and processing time, divided by the number of jobs. Therefore, option B - total flow time divided by the number of jobs is the correct choice. Option A is incorrect because it only considers processing time and ignores waiting time. Option C is incorrect because it considers the ratio of total flow time to processing time, which is not the average job flow time. Option D is incorrect because it includes late time, which is not a part of the flow time. Option E is incorrect because it includes both flow time and late time, which are not the same thing.
