Respuesta :

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

[tex]500 \div 20 = 25[/tex]

The elevator is descending 25 ft/s.

Answer:

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

Step-by-step 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 = [tex]\frac{500}{20}[/tex]feet

                                                        = [tex]25[/tex]feet

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