Question

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

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.

$slope= \frac{ChangeInHeight}{ChangeInHorizontalDistance} = \frac{2}{5}= \frac{4feet}{x} \\ \frac{2}{5} = \frac{4feet}{x} \\ 2x = 20feet \\ x = 10feet$
