I want 3.12 solution, thanks

Problem 3-11 A certain batch of parts is routed through six machines in a batch production plant. The setup and operation times for each machine are given in the table below. Batch size is 200 and the average nonoperation time per machine is 15 hr. Determine (a) manufacturing lead time and (b) hourly production rate for operation 4. Machine 1 2 3 4 5 Setup time (hours) 5 3 6 5 3 Operation time (min) 3.0 3.3 8.2 3.9 4.5 2.3 4 Problem 3-12 Suppose the part in the previous problem is made in very large quantities on a production line in which an automated work handling system is used to transfer parts between machines. Transfer time between stations is 30 sec. Total time required to set up the entire line is 120 hr. Assume that the operation times at the individual machines remain the same as in the previous problem. Determine (a) manufacturing lead time for a part coming off the line, (b) production rate for operation 3, (c) theoretical production rate for the entire production line. (d) How long would it take to produce 15,000 parts after the setup has been completed
