To find the rate at which the hose fills the pool in gallons per minute, you can use the formula:
\[ \text{Rate} = \frac{\text{Total Volume}}{\text{Time}} \]
Given that the total volume of the pool is 441 gallons and the time taken to fill the pool is 49 minutes, the calculation would be:
\[ \text{Rate} = \frac{441 \text{ gallons}}{49 \text{ minutes}} = 9 \text{ gallons per minute} \]
So, the hose fills the pool at a rate of 9 gallons per minute.
