Arectangular swimming pool with a flat bottom is 20 feet by 12 feet. how long will it take to fill the swimming pool to 5 feet if water is being pumped into the pool at 30 cubic feet per minute?

The given dimensions of the rectangular swimming pool are =

Length = 20 feet

Width = 12 feet

Height upto which the water should be filled up = 5 feet

So, the total volume of water needed to fill the pool will be =

cubic feet

The water is pumped at a speed of = 30 cubic feet per minute.

So, to fill 1200 cubic feet, the time taken will be =

Hence, it will take 40 minutes to fill the pool.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
