To find the unit rate of gallons per minute, you can divide the total gallons of water pumped by the total time in minutes.
Given:
- Total gallons of water = 330 gallons
- Total time = 22 minutes
Now, calculate the unit rate:
\[ \text{Unit Rate} = \frac{330 \text{ gallons}}{22 \text{ minutes}} = 15 \text{ gallons per minute} \]
So, the unit rate is 15 gallons per minute.
