Final answer:
To calculate the Belt Run Time (BRT) for a sort shift range, subtract the total non-operational times from the total shift time. In the student's question, the BRT is 473 minutes within a 9-hour shift after accounting for walk time, break, lunch, and last induct/stow down.
Step-by-step explanation:
The student's question involves calculating the Belt Run Time (BRT) within a given sort shift range and accounting for various periods of non-operation, such as walk time, break, lunch, and the last induct/stow down. To find the BRT, you need to consider the total time frame and subtract any non-operational times. Here, the shift range is from 01:00 to 10:00. First, we add the total non-operational times: walk time (01:00 to 01:07), break (03:00 to 03:15), lunch (05:15 to 05:45), and last induct/stow down (09:45 to 10:00).
We calculate these durations: Walk time is 7 minutes, break is 15 minutes, lunch is 30 minutes, and the last induct/stow down is 15 minutes. Adding these together gives us a total of 67 minutes of non-operational time. To find the sum of the BRT, we subtract the non-operational time from the total time of the shift: 9 hours (540 minutes) minus 67 minutes equals 473 minutes of BRT.
Lastly, the number '7.88' provided in the question is unclear in its context, and therefore, it's not included in the calculation. Assuming all the given and calculated times are correct, the total BRT for the sort shift range is 473 minutes.
