Question

Tori ran 4/5 Mile in 1/5 hour. write an equation for the distance in miles Y that she ran in X hours if she ran at a constant rate​

Answer 1

`y=4x`

Explanation:

Let

y ----> the distance in miles

x ----> the time in hours

using proportion

`(y)/(x)=((4/5))/((1/5))`

Simplify

`(y)/(x)=(4)/(1)`

`y=4x`

This is a linear direct variation

The unit rate or speed is the slope of the linear equation

The unit rate is 4 miles/hour
