Question

On a -foot 600 stretch of highway through the mountains, the road rises by a total of 30 feet. Find the slope of the road.

Answer 1

Given:

`\begin{gathered} stretch\text{ }distance=600feet \\ rises\text{ }distance=30feet \end{gathered}`

To Determine: The slope

The slope is given by the formula

`slope(s)=\frac{rises\text{ distance}}{stretch\text{ distance}}`

Substitute the given into the formula

`\begin{gathered} s=(30feet)/(600feet) \\ s=(1)/(20) \end{gathered}`
`s=0.05`

Hence, the slope is 1/20 or 0.05
