Question

A ramp used to remove furniture from a moving truck has a slope of 2/5.

The height of the ramp is 4 feet. How far does the base of the ramp extend from the end of the truck?

Answer 1

Remember that slope is change in y (height) over change in x (horizontal distance). We set up a proportion to find the horizontal distance from the base of the ramp to the end of the truck.


`slope= (ChangeInHeight)/(ChangeInHorizontalDistance) = (2)/(5)= (4feet)/(x) \\ (2)/(5) = (4feet)/(x) \\ 2x = 20feet \\ x = 10feet`
