The percent grade of a road gives the elevation change of a road
compared to the horizontal distance covered. For example, an 8% grade
means that the road elevation changes 8 feet for every 100 feet of
horizontal distance. Jason turns onto a road and sees the road sign
shown.
1) Sketch a picture to model the situation.
8% Grade
Next 7 miles
2) What angle does the road make with level ground? Show your thinking.
3) Determine the elevation gain of the entire stretch of road, to the nearest foot.
(Hint: 1 mile = 5,280 feet)
