Answer :
Final answer:
The total feet of chains produced in the week is 4200 feet. When this is divided by the total operating hours in the week (60 hours), we get an average of 70 feet of chain produced per operating hour.
Explanation:
To calculate the number of feet of chain produced per operating hour, we first need to find the total feet of chain produced and the total operating hours in a week. The total feet of chains produced is 862 + 905 + 792 + 825 + 816 = 4200 feet. The equipment operates 5 days a week for 12 hours each day, hence total operating hours equals 5 * 12 = 60 hours in a week.
Next, we divide the total feet of chain by the total operating hours to get the feet of chain produced per operating hour. Hence, 4200 feet divided by 60 hours equals 70 feet/hour.
