Math Homework Help Part 2! :)?
West of a city, a certain eastbound route is straight and makes a steep descent toward the city. The highway has a 9% grade, which means that its slope is -9/100
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 in miles? (Round your answer to two decimal places.)
I tried this method that you gave (dx = -1000/(-9/100) = 11111.11 ft) and it said it was incorrect why is that?

dy/dx = -9/100
descended a distance of 1000 ft. = dy = -1000 ft.
dx = -1000/(-9/100) = 11111.11 ft
