When designing and building roads, engineers and surveyors need to be concerned about the grade of the road. The grade, usually expressed as a percent, is one way to describe the steepness of the finished surface of the road. For example, a 5% grade means that the road has a slope (rise over run) of 0.05 = 5/100. A.If a road has a 5% upward grade over a 1000-foot run how much higher will you be at the end of that run than at the beginning? B.What is the grade of a road that rises 26 feet over a distance of 500 feet?This question is from textbook Answer by Earlsdon(6287)   (Show Source): You can put this solution on YOUR website!A. An upward grade of 5% means that the road rises 5 feet for every 100 fet of distance from the beginning. So, using a proportion, you can write: to find the ending height. feet higher. B. If the road rises 26 feet in 500 feet of distance, then the grade is: = 5.2%
