A water tank has a capacity of 4000 gallons. Mack connects a pipe to the tank that fills the tank with water at the rate of 10 gallons per hour. How long will it take to fill the tank to 3/4 of its capacity?

How many gallons are in the tank? ** 3/4 of the water tank is 3/4*4000 = <<3/4*4000=3000>>3000
How long will it take to fill the tank to 3/4 of its capacity? ** If the pipe fills the tank with water at the rate of 10 gallons per hour, it will take 3000/10 = <<3000/10=300>>300 hours to fill the tank to 3/4 of its capacity
