The slope of a ramp from the sidewalk to the street has to be [tex]\frac{1}{20}[/tex]. The height of the ramp is 2.5 inches. What is the horizontal length (in inches) of the ramp?

Question

psjury · Answer

The ratio is 1:20 so if you need to go up 2.5 inches you need to travel 2.5x20 inches horizontally. 2.5x20=50 inches.

psjury · Answer

The horizontal length of the ramp is calculated using the slope ratio of 20 1 ​ and the height of 2.5 inches. With the formula, the horizontal length (run) resulted in 50 inches. Therefore, the ramp extends 50 inches horizontally.
