Question

A car travels a distance of d km in t hours. The formula that

relates d to tis d = kt. What kind of variation is it?​

Answer 1

Direct Variation

Explanation:

Given: A car travels at a distance of
`d` km. The formula that relates
`d` to
`t` is
`d=kt`

To find: kind of variation

Solution:

The formula that relates
`d` to
`t` is
`d=kt`

Here,
`k` is a constant of proportionality.

Constant of proportionality is also called as constant of variation.

`d` varies directly as
`t`.

Therefore, this is a direct variation.
