QuestionMr. Gill's pump drains water at $-2 \frac{1}{4}$ inches/hour. A stronger pump drains $2 \frac{1}{2}$ times faster. Find the rate.

Studdy Solution
Convert the improper fraction $-\frac{45}{}$ to a mixed number to make it easier to understand.
$$-\frac{45}{} = -5 \frac{5}{}$$The stronger pump would change the water level by $-5 \frac{5}{}$ inches per hour. So, the answer is (A) $-5 \frac{5}{}$ inches.
