Explanation:

The student is interested in finding how long it will take to fill a 300-gallon swimming pool at a rate of 4 gallons per minute. To calculate this, you divide the total number of gallons needed to fill the pool by the rate at which the pool is being filled. Here's the step-by-step calculation:

  1. Determine the capacity of the pool: 300 gallons.
  2. Determine the fill rate: 4 gallons per minute.
  3. Calculate the time to fill: Time = Pool Capacity / Fill Rate = 300 gallons / 4 gallons per minute.
  4. Perform the division: 300 / 4 = 75 minutes.

Therefore, it will take 75 minutes to fill a 300-gallon swimming pool at a rate of 4 gallons per minute.
