Question 157577: The steepness, or grade, of a road is expressed as a percent. If a road rises 3 feet for every 24 horizontal feet, what is the sope of the road? what percent grade is this? Answer by Earlsdon(6291) (Show Source):
You can put this solution on YOUR website! Remember...slope = rise over run.
Rise is 3 ft. and run is 24 ft, so slope = 3/24. Simplify to 1/8 and the decimal equaivalent is 0.125 which, changed to a percent = 12.5%
The grade is 12.5%
