A road with a rise of 2% over a 100 ft run would have a percent incline of approximately:

• A. 0.2%
• B. 2%
• C. 0.02%
• D. 20%

Answer: (B)

Percent incline (grade) is found by comparing how much vertical rise there is over a horizontal distance, then multiplying by 100. If the run is 100 ft and the rise is 2% of that distance, the vertical rise is 2% of 100 ft, which is 2 ft. So the slope is 2 ft rise over 100 ft run, i.e., 2/100 = 0.02, which equals 2%. This matches the given scenario, so the incline is approximately 2%. The other options would require much smaller or larger rises per 100 ft (0.2% would be 0.2 ft rise per 100 ft, 0.02% would be 0.02 ft per 100 ft, and 20% would be 20 ft per 100 ft).
