wheelchair ramps are required to adhere to a slope of 1:12, for every 1 inch of rise, the horizontal run must be 12 inches. The vertical distance from the ground to the platform is 1 1/2 feet. What will the distance x in feet need to be to meet the guidelines?

Answer:

Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade)
