Suppose that in 9 minutes 72 , gallons of water came out of a pipe.

Question

What was the rate in gallons per minute?

Answer 1

To find the rate in gallons per minute, you divide the total amount of water (in gallons) by the total time (in minutes).

Here, the total amount of water is 72 gallons, and the time is 9 minutes.

\[ \text{Rate} = \frac{\text{Total gallons}}{\text{Total minutes}} = \frac{72 \text{ gallons}}{9 \text{ minutes}} = 8 \text{ gallons per minute} \]

So, the rate is 8 gallons per minute.
