To find the rate at which the swimming pool fills, we can use the formula:
\[
\text{Rate} = \frac{\text{Total Volume}}{\text{Time}}
\]
In this case, the total volume of water is 135 gallons, and the time taken is 15 minutes. Plugging in the values:
\[
\text{Rate} = \frac{135 \text{ gallons}}{15 \text{ minutes}} = 9 \text{ gallons per minute}
\]
So the swimming pool fills at a rate of 9 gallons per minute.
The correct answer is:
**D. 9 gallons per minute**
\[
\text{Rate} = \frac{\text{Total Volume}}{\text{Time}}
\]
In this case, the total volume of water is 135 gallons, and the time taken is 15 minutes. Plugging in the values:
\[
\text{Rate} = \frac{135 \text{ gallons}}{15 \text{ minutes}} = 9 \text{ gallons per minute}
\]
So the swimming pool fills at a rate of 9 gallons per minute.
The correct answer is:
**D. 9 gallons per minute**
