22. Consider a serial production process with 2 stations: The products are first processed at Station A, and then at Station B. Station A can process 20 units per hour. Station B can process 16 units per hour. Suppose Station A works nonstop for 8 hours. How long does Station B have to be active to process all units produced at Station A?

1. 10 hours

2. 12 hours

3. 15 hours

4. The answer cannot be computed with the available information

5. 8 hours

23. Consider a serial production process. Worker A processes the product first and passes it to worker B. Worker B completes the second phase of production and then passes the product to worker C for final processing. Worker A can process 1 unit in 8 minutes. Worker B can process 1 unit in 2 minutes. Worker C can process 1 unit in 5 minutes. Can the company layoff one worker and assign their work to another worker without affecting the current throughput rate of the process?

1. Yes, layoff worker A and assign their work to Worker C.

2. Yes, layoff worker A and assign their work to Worker B.

3. Yes, layoff Work C and assign their work to Worker A.

4. Yes, layoff worker B and assign their work to Worker C.

5. No, the throughput rate will be affected if one worker is laid off and their work is assigned to one of the remaining two workers.
