If Rise is 60 ft and Run is 240 ft, what is the slope percent?

Explanation:
Slope percent tells you how steep something is by comparing vertical rise to horizontal run, expressed as a percent. It’s calculated as rise divided by run, times 100. Here, rise is 60 ft and run is 240 ft. So the slope percent is 60 / 240 = 0.25, and 0.25 × 100% = 25%. This means for every 240 ft of horizontal distance, the ground climbs 60 ft. Quick cross-checks show that to get 20%, you’d need a rise of 48 ft over 240 ft; for 15%, 36 ft; for 10%, 24 ft—none match the given rise.
