Question: 24 gallons per second of water flows down a waterfall. If you have an empty basin that can hold 260 gallons of water. The basin leaks water at 4 gallons per second. how long would it take to fill the basin with water from the waterfall in seconds? Is final answer 13?
Answer: 24 gallons in minus 4 gallons out is 24-4=<<24-4=20>>20 gallons per second
260 gallons divided by 20 gallons per second 260/20 = <<260/20=13>>13 seconds
