Aunt is feeling a tank with water at a rate of 3 gallons per minute. The tank already had 130 gallons of water in it supposed to tank I was a total of 280 gallons of water. How much longer will it take aunt to fill the tank?

Answer 1

The aunt is currently filling the tank at a rate of 3 gallons per minute.

To fill the tank from 130 gallons to 280 gallons, she needs an additional 280 - 130 = 150 gallons of water.

At a rate of 3 gallons per minute, it will take her 150 / 3 = 50 minutes to fill the remaining water in the tank.

Therefore, it will take her 50 minutes longer to fill the tank completely.
