Two water tanks, X and Y, were drained simultaneously. If X contained 30 more gallons of water than Y, and both tanks became empty at the same time, how long did it take the tanks to empty?

1) For ever gallon drained from tank Y, 2 gallons were drained from tank X.

2) Tank Y was drained at a constant rate of 20 gallons per hour.

Like they used to say in math class, please show your work! OA to come!
