Question

An elevator travels down from the top floor of a skyscraper. Its height, in feet, is givenby the equation h = 800 – 18t, where h represents the elevator's height, in feet,and t represents the time, in seconds. What could the number 800 represent in theequation?

Answer 1

We have an expression for the height in function of time:

`h(t)=800-18t`

The value 800 correspond to the height when t=0, so we can conclude that 800 is the initial heigth. This initial height is the height of the top floor of the skyscraper.

Answer: 800 is the initial height, that correspond to the height of the top floor of the skyscraper.
