Question

A water tank holds 24000 gallons. How many hours will it take for 2/3 of the water to be used if the water is used at an average rate of 650 gallons a day?

Answer 1

First, determine what 2/3 of 24000 gallons is.  That's 18000 gallons.

Next, divide this   18000 gallon amount by 650 gallons/da:

 18000 gal
----------------- =  27.69 days, or about 28 days.
650 gal/day

Answer 2

24000 Gallons / 650(gallons per day) =36.92 days to fill it fully. Now take 36.92 and multiply by (2/3)=24.61 days. (.61 days = 14 Hours and 36 minutes)
