You can put this solution on YOUR website! The highway has a 6% grade on descent, which means it's slope is - 6/100. Driving on this road, you notice from elevation signs that you have descended a distance of 1000 ft. What is the change in your horizontal distance?
------------------
slope = vertical change/horizontal change
----------------------------
Use a proportion:
1000/x = 6/100
x = 100000/6 = 16,666.67 ft (horizontal distance)
