Question

A U.S. disability regulation requires that wheelchair ramps have a slope no greater than 1/12. Would a ramp with the length of 5 meters and a height of 0.25 meters meet this requirement? If so, explain how you know it will meet the regulation. If not, how long should the ramp be to have the given height?

Answer 1

Given:

Slope of ramp is:

`\text{slope = }(1)/(12)`

Length of ramp is 5 meter.

Height of ramp is 0.25 meter.

Slope is define as hight over length so slope is:

`\text{slope}=\frac{\text{ Height}}{\text{ Length}}`

If the height is 0.25 then maximum length of ramp is:

`\begin{gathered} =0.25*12 \\ =3 \end{gathered}`

For meet the regulation length of ramp is 3 meter.
