The unit rate is obtained by dividing the amount of work done by the unit time. In the problem, we are already given the total number of parts manufactured (amount of work done) and the total amount of time to manufacture (7 hours).
Obtaining the unit rate is as simple as dividing 1116 parts by 7 hours, as shown below:
Unit rate = 1116 parts / 7 hours
Unit rate = 159.42857
Therefore the unit rate is approximately 159 parts/h.
