POTW #5
A water tub that holds 1000 gallons is empty. The owner wants to fill the tub, so he turns on the water to fill the tub. Water is filling the tub at five gallons per minute. Five minutes later the tub starting filling with water, a mischivious child turns on the drain, which drains water away at two gallons per minute. How much more time did it take for the tub to fill with the drain on than without it. (In other words, take the time that it took to fill the tub witht the drain on and stract it from the time it would have taken if the drain was never turned on.) Give your answer in hours and minutes.
Hint: Use ALGEBRA! Make an equation.
Difficulty level: 5
Source: Original, but the idea came from last year's math class at Chinese School.
This is the very last POTW for this competition. The winner gets a prize. (Don't expect anything that's worth more than a dollar.) Even if you are very behind, this is your chance to catch up. First place is worth 25 points!

And don't try to hide your own personal problems by analyzing other people's problems and using that information against them to make them look bad. This is probably the reason why your name is guesswhoiam since you are hiding something that will be revealed if you tell us who you are that shows you in a state of weakness.
