Question 348357: When you are traveling in the mountains, you will often see signs about the grade of the road. If you are traveling downhill and you see a sign indicating that the road has a 7% grade, then the slope of the road is -7/100.
Suppose that you are driving downhill on a road with a 8% grade. If you have descended 750 feet, what is the change in your horizontal distance?

You can put this solution on YOUR website! Suppose that you are driving downhill on a road with a 8% grade. If you have descended 750 feet, what is the change in your horizontal distance?
------
h/750 = 100/8
h = 75000/8
horizontal distance = 9375 ft.
