Please explain how you get the last answer if workstations 2& 3 process concurrently with workstations 4 and 5 what is the throughput time? (explain with steps please)

Consider the following linear process. What is the steady state capacity of the above linear process? units/hour What is the throughput time of the above linear process? minutes If workstation 2&3 process concurrently with workstation 4 and 5 as shown above, what is the steady state hourly capacity? units/hour If workstation 2&3 process concurrently with workstation 4 and 5 as shown above, what is the throughput time? x minutes
