a tank holds 500 gallons of water. it drains 24 gallons in 6 minutes. what is the change in water in 1 minute

To find the change in water in 1 minute, you can first calculate the rate at which the water drains.

The tank drains 24 gallons in 6 minutes. Therefore, the rate of drainage can be calculated as follows:

\[
\text{Rate} = \frac{24 \text{ gallons}}{6 \text{ minutes}} = 4 \text{ gallons per minute}
\]

Thus, the change in water in 1 minute is 4 gallons. Since the tank is draining, the change is negative:

\[
\text{Change in water in 1 minute} = -4 \text{ gallons}
\]
