Water evaporates at the rate of two liters per hour per one [#permalink]  10 Dec 2007, 07:44
Water evaporates at the rate of two liters per hour per one square mater of surface. How long will it take to evaporate 30 liters of water from a 56 ton swimming pool if the depth of the pool is 2 meters?

Not sure how the conversion from ton to meters works... I think that if such a Q showed up on the GMAT, it would give us the conversion...
