The percent grade of a highway is the amount that the highway raises or falls in a given horizontal distance. For example, a highway with a four percent grade rises 0.04 mile for every 1 mile of horizontal distance.
a. How many feet does a highway with a six percent grade rise in 2.5 miles of horizontal distance?
b. How many feet would a highway with a six percent grade rise in 90 miles of horizontal distance if the grade remained constant?
c. How is percent grade related to slope?
