Question

one jug holds 7/8 gallons of water. if a faucet can release 16 gallons in 8 minutes. how long would it take to fill one jug with water?

Answer 1

16 gallons in 8 minutes = 16/8 gallons per minute, or 2 gpm. Lets say the jug could hold 8/8 gallons, or one gallon. It would follow then that it would take 1 gallon/2gallons per minute = 1/2 minutes (the gallon units cancel out) for the jug to fill.

Answer 2

Then taking the given 7/8 gallon capacity, you would have (7/8gal)/2gpm

Answer 3

This is a proportion problem.
16 gal : 8 min = 7/8 gal = x min
16/8 = (7/8)/x
Cross multiply and solve for x.
