Question

The slope for a wheelchair ramp for a home has to be 1/2. if the vertical distance from the ground to the door bottom is 3 ft, find the distance the ramp has to extend from the home in order to comply with the needed slope. write your work in the answer box.

Answer 1

6 ft

Explanation:

slope =
`(rise)/(run)` ( rise is vertical height and run is horizontal distance )

here vertical height = 3 and slope =
`(1)/(2)` , then

`(1)/(2)` =
`(3)/(run)` ( cross- multiply )

run = 2 × 3 = 6 ft
