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)
