Chapter 8.6, Problem 9PPS

To determine

To find: the slope of a road that

Answer to Problem 9PPS

The slope of the road is: $\frac{1}{9}$

Explanation of Solution

Given:

road rise 5 feet vertically for every 45 foot horizontal increase.

Calculation:

Slope is the ratio of the rise or the vertical change, to the run, or the horizontal change. Since, the vertical change is 5 feet and horizontal change is 45 feet

Thus, slope of the road is:

  $\begin{array}{c}\text{slpoe}=\frac{5}{45}\\ =\frac{1}{9}\end{array}$

Conclusion:

Therefore, the slope of the road is: $\frac{1}{9}$
