if you know the rate of a water leak in gallons per hour, how can you find the number if hours it takes for 1 gallon to leak out?

Thanks! 

Amount  =  Rate x Time

For instance, if you know that water leaks at the rate of 2.3 liters per hour, to find out the time that it take for 1 liter to leak:       Amount  =  Rate x Time     --->     1 liter  =  2.3 liters/hour x Time

Divide both sides by 2.3 liters/hour             --->      1/2.3 hours  =  Time

                                                                    --->      0.435 hours  =  Time

(To change decimal hours into minutes, multiply by  60:  0.435 hours x 60 minutes/hour  =  26 minutes.)
