To determine the unit rate (the ratio of two measurements), you need to express the number of revolutions per unit of time.
In this case, you have:
- Total revolutions: 960
- Total time: 30 minutes
To find the unit rate (revolutions per minute), divide the total number of revolutions by the total time in minutes:
\[ \text{Unit Rate} = \frac{\text{Total Revolutions}}{\text{Total Time}} = \frac{960 \text{ revolutions}}{30 \text{ minutes}} = 32 \text{ revolutions per minute} \]
So, the unit rate is 32 revolutions per minute.
