If a road has a 4% grade and rises 200 feet, what is the run?

5

8

5000

8000

5000

Step-by-step explanation:

According to Wikipedia, the percent measureof a road grade is 100 times rise over run. in your case you know everything but run, so let's set up an equation

4=100 * 200 / run

Now just use algebra

4 = 20000 / run

run * 4 = 20000

run = 20000/4

run = 5000
