A production process at Kenneth Day Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are inparallel).

1.8 units/hr 5 units/hr Assembly 0.8 units/hr Sawing Sanding o o Assembly Welding 2.5 units/hr 0.8 units/hr Drilling 6 units/hr Assembly 0.8 units/hr a) Sawing is the bottleneck. b) The bottleneck time is 33.33 minutes per unit (round your response to two decimal places). c) The throughput time of the overall system is minutes (round your response to two decimal places)
