First find how many gallons one-fourth of the pool is to find how much has been filled within 15 minutes.

One-fourth of 300 gallons is 75 gallons. Within 15 minutes, 75 gallons of water have entered the pool.

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

5 gallons/minute

If one-fourth of the pool is filled in 15 minutes, how long would it take for four-fourths (one whole) of the pool to be filled?
