Answer :
Final answer:
To find the average length of chain produced per operating hour in a week, divide the total feet of chain produced (which we're assuming is X feet) by the total operating hours, which is 60 hours for a 5-day week with 12 operating hours each day.
Explanation:
The student needs to find out the total feet of chain produced per operating hour in a week. To do this, they need to make use of the total hours of operation for the equipment. As per the question, the equipment operates for 5 days a week and 12 hours each day. Therefore, the total operating hours for a week would be 5 days * 12 hours = 60 hours.
We do not have the actual production numbers from the table in your question, so let's assume that X feet of chain were produced last week. To find the average length of chain produced per operating hour, they need to divide the total feet of chain produced by the total operating hours. That is, the average length = X feet / 60 hours.
This formula allows the student to find out the average length of chain produced per operating hour given any production numbers.
