Step-by-step explanation:

Rate of Change

If two variables x and t are to be related as the rate x changes when t changes, it can be expressed as:

[tex]\displaystyle v=\frac{x}{t}[/tex]

Hans takes a ride in the elevator down from the 86th floor to the first floor, a distance of x=320 meters in t=50 seconds. The rate of descent is

[tex]\displaystyle v=\frac{320}{50}[/tex]

[tex]v=6.4\ m/s[/tex]
