** A wheelchair ramp is to be built at the town library. If the entrance to the library is 18 in. above ground, and the slope of the ramp is ****, how far out from the building will the ramp start ?**

The ramp will start 270 inches apart from the building.

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 $\frac{1}{15}$.

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

According to the question we consider this figure below:

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

So,

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

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