A batch manufacturing operation has a machine setup time of 5.0 hours and a manufacturing time of 1.70 min per cycle. Six components are produced each cycle. Part handling time each cycle is 40 sec. It consists of the worker obtaining six starting work units from a parts tray, loading them into the machine, and then after processing, unloading the completed units and placing them into the same tray. Each tray holds 30 work units. When all of the starting work units have been replaced with completed units, the tray of completed parts is moved aside and a new tray of starting parts is moved into position at the machine. This irregular work element takes 5.0 min. Batch quantity is 2700 units.

Determine
i. Average cycle time
ii. Time to complete the batch
iii. Average production rate.
