## Question:

You rollerblade at an average speed of 8 miles per hour. The number of miles m you rollerblade during h hours is modeled by m= 8h. Do these two quantities have a direct variation?

## Variation:

Variation in math basically describes how one variable is affected by another. Direct variation, inverse variation, joint variation, combined variation and partial variation are examples of variation in math.

In the rate of rollerblading given at an average speed of 8 miles per hour modeled by the equation {eq}m = 8h {/eq} shows a direct variation between {eq}{/eq} and {eq}h {/eq}. This means that when {eq}h {/eq} increases, the value of {eq}m {/eq} also increases by a factor of {eq}8 {/eq}.
