Please explain the step by step solution for e)

The Action Toy Company has decided to manufacture a new train set, the production of which is broken into six steps. The demand for the train is 4,500 units per 40-hour workweek: Predecessors Task A B Performance Time (seconds) 24 27 14 14 12 27 D A A B, C DE E F This exercise only contains parts b, c, d, e, and f. b) Given the demand, the cycle time for the production of the new train set = 32 seconds (round your response to one decimal place). c) The theoretical minimum number of workstations = 4 (round your response up to the next whole number). d) Using the longest operation time rule, the assignment of tasks to workstations should be: (Hint: Number workstations sequentially in terms of precedence relationships and combine any applicable tasks.) Task Workstation # Station 1 Station 2 Station 3 Station 3 Station 4 Station 5 Were you able to assign all the tasks to the theoretical minimum number of workstations? No e) The total idle time per cycle for the process = seconds (enter your response as a whole number)
