The Run of a Pipe Is 200 Feet and It Drops 2 Feet. What Is the Rise Over Run Slope in Percent?

Explanation:
Slope percent is the vertical change divided by the horizontal run, multiplied by 100 to express it as a percentage. Here the pipe drops 2 feet over 200 feet of run. So 2 ÷ 200 = 0.01, and 0.01 × 100 = 1%. The slope is 1%. Over 200 feet, a 1% grade means about a 2-foot drop, which matches the given rise. The other options correspond to different drops for the same 200-foot length: 0.5% would be about a 1-foot drop, 2% would be about 4 feet, and 5% would be about 10 feet.
