Question 619913: A motorcycle daredevil is planning a stunt to perform at a county fair. A ramp must be built to give him a 20% grade, or slope. If the vertical height at the end of the ramp must be 15 ft to assure that the stunt is a success, what must be the length of the horizontal run?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
Slope Grade = (Rise/Run)*100
20 = (15/x)*100
20 = 1500/x
20x = 1500
x = 1500/20
x = 75
So the length of the horizontal run must be 75 feet
