4 A process with five steps has a cycle time of 2.8 minutes per unit. The only inventory in the system is held before the last station, where 31 units of inventory are maintained. A defective unit is produced at the second station but is not detected until final inspection (after the fifth station). What is the information turnaround time (in minutes)? (Example: A process with five steps has a cycle time of 2.6 minutes per unit. The only inventory in the system is held before the last station, where 23 units of inventory are maintained. A defective unit is produced at the third station but is not detected until final inspection (after the fifth station). Example explanation: A defective unit produced by the third workstation must journey through the remaining two stations and wait in inventory before being observed in inspection. Therefore, the unit will remain undetected for 2 x 2.6+23 x 2.6= 5.2 +59.8= 65 minutes.) Note: Round your answer to 1 decimal place. Information turnaround time minutes
