Question

The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V. Write the direct variation equation for the scenario above.

Answer 1

`D=kV^2`

Explanation:

In this problem, it is given that,

The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V.

We need to write the direct variation equation for the scenario above. It can be given by :

`D\propto V^2`

To remove the constant of proportionality, we put k.

`D=kV^2`

k is any constant

Hence, this is the required solution.
