Beth is filling a small backyard pool with a garden hose. The pool holds $30$ gallons of water. After $5$ minutes, the pool is about one fourth full.

1. Assuming that the water is flowing at a constant rate, about how much water is going into the pool each minute?

   Step 1(a):

   First, find how many gallons one-fourth of the pool is.

   $\frac{30 \text{Gallons}}{4}=7.5\text{ Gallons}$

   Step 2(a):

   To find the rate per minute, divide the amount by the time.

   $\frac{7.5\text{ Gallons}}{5\text{ Minutes}}$

   Answer (a):

   $1.5\frac{\text{Gallons}}{\text{Minute}}$

2. About how long will it take to fill the pool?

   Hint (b):

   If one fourth of the pool is filled in $5$ minutes, how long would it take for four fourths (one whole) of the pool to be filled?
