Problema Solution
The slope of a ramp from the sidewalk to the street has to be 1/20. The height of a ramp is 2.5 inches. What is the horizontal length (in inches) of the ramp?
Answer provided by our tutors
let
h = 2.5 in the height of the ramp
d = the horizontal length (in inches) of the ramp
The slope of a ramp from the sidewalk to the street = 2.5/d
2.5/d = 1/20
by solving we find:
d = 50 in
