Solution
The average job flow time refers to the average time taken by the job and the Waiting time involved in it . It is also a tool used to measure the effectiveness of scheduling as it states the efficiency of process scheduled which process involves less waiting time .
Average flow time =( total process time + total waiting time) ÷ total number of jobs
= (7+13+20+24+27) ÷ 5
= 18.2 hrs
