Question

The water in Jana's swimming pool is 50 inches deep. Each minute the water loses 0.05 inch of depth. Write an algebraic expression that represents the depth of the water in the pool after h hours. Then simplify your expression.

Answer 1

Answer: Our required expression will be

$50-3h$

Explanation:

Since we have given that

Depth of water in Jana's swimming pool = 50 inches

Each minute the water losses 0.05 inches of depth

Let the number of hours be h

So, we have

in 1 minute , 0.05 inches of depth of water is reduced.

in  60 minutes,

$0.05\times 60=3\text{ inches is lost}$

So, in h hour, 3h inches of depth of water is reduced.

So, Our required expression will be

$50-3h$
