Question

Water flows at a rate of 0.16 liters per second into a tank of volume 200 gallons. Given that 1 gallon equals 3.79 liters, express in hours the time required to fill the tank, if it is empty to start with.

Answer 1

It will take about 36 hours to fill up the tank

Answer 2

3.79 litres x 200 = 758 litres
758 litres ÷ 0.16 litres = 4737.5 seconds
4737.5 ÷ 60 = 78.9583 minutes
78.9583 minutes is equal to approximately 1 hour 20 minutes, or 1.3 hours
