Answer 1

To find the change in the amount of water in gallons in 1 minute, we first determine how many gallons are removed in 1 minute.

The pump removes 250 gallons in 5 minutes, so we calculate the rate of removal per minute:

\[
\text{Rate of removal} = \frac{250 \text{ gallons}}{5 \text{ minutes}} = 50 \text{ gallons per minute}
\]

Since the pump is removing water, the change in the amount of water is negative. Therefore, the change in the amount of water in 1 minute is:

\[
\text{Change} = -50 \text{ gallons}
\]

So the correct response is:

−50
