Question

The slope of a wheelchair ramp for a home has to be 112112. If the vertical distance from the ground to the door bottom is 2.5 ft, find the distance the ramp has to extend from the home in order to comply with the needed slope.

Answer 1

slope = vertical distance / horizontal distance
1 1/2 = 2.5 / horizontal distance
horizontal distance = 2(2.5)/3 = 5/3 = 1 2/3 feet
