Final answer:
Inmates should not be required to work more than 42.5 hours per week, except in an emergency.
Step-by-step explanation:
The question is about the maximum number of hours per week that inmates should be required to work, except in an emergency.
According to labor statistics, the average number of hours worked per week by U.S. workers in 2013 was 38.5, and for full-time workers, it was 42.5 hours per week.
Therefore, inmates should not be required to work more than 42.5 hours per week, except in an emergency.
