TABLE OF CONTENTS

Step-1 – Given

A wheelchair ramp is to be built at the town library. If the entrance to the library is 18 inch above ground and the slope of the ramp is $\frac{1}{15}$ .

Step-2 – To determine

We have to find how far out from the building, the ramp will start.

Step-3 – Calculation

According to the question we consider this figure below:

Let us assume, x= the distance between the building and the ramp.

So,

$\begin{array}{l} slope = \tan θ = \frac{18}{x} = \frac{1}{15} \\ \frac{18}{x} = \frac{1}{15} \\ x = 18 \times 15 = 270 in. \end{array}$

So, the ramp will start 270 inches apart from the building.
