Answer:
16 minutes
Step-by-step explanation:
Because the tank already holds 5 gallons of water, you only need to find the number of minutes to fill 4 gallons of water.
Because it fills at a rate of 1/4 gallons a minute, it takes 4 minutes per gallon of water.
Since we are dealing with 4 gallons of water to be filled, we multiply 4 · 4 to get the number of minutes.
4 · 4 = 16
16 minutes
