Consider the following production process. The process consists of 29 steps and operates at a cycle time of 0.78 min/unit. Their most error prone operation is step 13. If each worker checks the work of the previous steps and there are on average roughly 105 units of inventory between step 13 and the end of the process, equally distributed across the remainder of the process, what is the average information turnaround time for a defect made at step 13 (in minutes)? (report your answer to 2 decimal places).
