Question

a hose fills a tank at rate of 30 gallons per minute. what is rate in liters per hour. 1 gallon=3.79 liters

Answer 1

If it fills 30 galons per minute, that means that it fills 30*60 minutes = 1800 gallons per hour.

We know that 1 gallon = 3,79 liters, so 1800 gallons per hour = 1800 * 3,79 liters = 6822 liters per hour.
