Find the unit rate for number of parts manufactured per hour if 1116 parts are made in 7 hours. Round to the nearest integer.

Question

209 parts/h

159 parts/h

127 parts/h

183 parts/h

Answer 1

To find the unit rate of parts manufactured per hour, divide the total number of parts by the total number of hours:

\[ \text{Unit Rate} = \frac{\text{Total Parts}}{\text{Total Hours}} = \frac{1116 \text{ parts}}{7 \text{ hours}} \approx 159.4286 \text{ parts/hour} \]

Rounding this to the nearest integer gives:

\[ 159 \text{ parts/hour} \]

So the unit rate is approximately 159 parts/h.
