The volume of a rectangular swimming pool is 840 cubic meters and water is flowing into the swimming pool. If the surface level of the water is rising at the rate of 0.5 meters per minute, what is the rate W, in cubic meters per minutes, at which the water is flowing into the swimming pool?
Select.
A) 0.125	B) 0.25	C) 0.5	D) 0.75	E) Not enough information to determine the rate
The correct answer is E.   There are not enough info to answer the question.   A 840 cubic meters rectangle is built from: height*length*width.   From the question we know the volume of the pool and the filling rate.   A pool can have a height of 10*width8.4*length10 and have a volume of 840 cubic meters, and it can have a height of 1 meter, width of 100 meters and length of 8.4. In both cases the pool will fill up in a different rate = Not enough information to determine the rate
