When Will Joe Finish?

     Joe bought a new fish aquarium. It holds 10 gallons of water and Joe wants to fill it three quarters of the way to the top. Unfortunately, Joe does not have a bucket to carry water to the aquarium. In fact the only thing he has is an eight ounce glass. He can fill the glass and dump it into the aquarium in 45 seconds. Joe starts filling the aquarium at noon, if he can keep up this constant rate at what time will he finish?
