Chapter 8.6, Problem 26STP

To determine

To find: The slope of the ramp.

Answer to Problem 26STP

The correct option is F.

Explanation of Solution

Given:

A vertical distance is 2.5 feet a horizontal distance is 30 feet.

F. $\frac{1}{12}$

G. $\frac{1}{11}$

H. $\frac{1}{9}$

J. $\frac{1}{8}$

Calculation:

Consider that a wheelchair rises a vertical distance of 2.5 feet over a horizontal distance of 30feet.

Slope is the ratio of the rise or the vertical change, to the run, or the horizontal change.

Since, the value of rise is 2.5 feet and the value of run is 30 feet.

Thus, slope of the ramp is:

  $\begin{array}{l}\text{slope=}\frac{\text{2}\text{.5}}{\text{30}}\\ =\frac{25}{300}\\ =\frac{1}{12}\end{array}$

Therefore the correct option is F.

Conclusion:

Therefore the correct option is F.
