Question

QuestionA local road rises 30 feet for every 483 feet of highway. What is the slope of the highway?

Answer 1

The slope can be found by the "rise over run", that is, is the change in variable y divided by the change in variable x.

In this question,

$\begin{gathered} slope=\frac{rise\text{ in the road}}{run\text{ in highway}} \\ \end{gathered}$

Substituting the values:

$\begin{gathered} slope=\frac{30}{483} \\ slope=0.06\text{ feet per feet of highway.} \end{gathered}$

Answer: 0.06 feet per feet of highway.
