Suppose that in 7 minutes, 49 gallons of water came out of a pipe.

To find the rate of water coming out of the pipe in gallons per minute, you can use the formula:

\[ \text{Rate} = \frac{\text{Total Gallons}}{\text{Time in Minutes}} \]

In this case, the total gallons of water is 49 gallons and the time is 7 minutes.

Calculating the rate:

\[ \text{Rate} = \frac{49 \text{ gallons}}{7 \text{ minutes}} = 7 \text{ gallons per minute} \]

Thus, the rate of water flow is 7 gallons per minute.
