The SPT (shortest processing time) sequence is the order in which the assignments are completed in order of shortest time required to complete each assignment. Using the data in Table J.2, the total processing time for all seven assignments is 225.5 hours. To find the average flow time, we divide this total by the number of assignments, which is 7. Therefore, the average flow time for all assignments scheduled in an SPT sequence is 32.14 hours (225.5 / 7 = 32.14). Thus, the best choice is option B.
