Question

An elevator descends 500 feet in 20 seconds.How would you express the change in the elevators height per second

Answer 1

The easiest way is to do some simple division, where 500 is the distance & 20 is the duration.


`500 / 20 = 25`

The elevator is descending 25 ft/s.

Answer 2

The change in the elevators height per second is 25 feet per second

Explanation:

Given :An elevator descends 500 feet in 20 seconds.

To Find :.How would you express the change in the elevators height per second

Solution :

An elevator descends in 20 seconds = 500 feet

An elevator descends in 1 seconds =
`(500)/(20)`feet

=
`25`feet

Hence The change in the elevators height per second is 25 feet per second
