Question

14.
Find the unit rate for number of parts manufactured per hour if 1116 parts are made in 7 hours. Round to the nearest integer.

Answer 1

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

Given:
- Total parts = 1116
- Total hours = 7

The calculation will be:

\[
\text{Unit rate} = \frac{\text{Total parts}}{\text{Total hours}} = \frac{1116}{7}
\]

Now performing the division:

\[
\frac{1116}{7} \approx 159.42857
\]

Rounding to the nearest integer gives us:

\[
\text{Unit rate} \approx 159
\]

Therefore, the unit rate for the number of parts manufactured per hour is **159 parts per hour**.
