The Americans with disabilities act requires that wheelchair ramps have a slope no greater than 1/12 what is the minimum horizontal length a 2 foot high ramp can have ?
rise/run = 2/L = 1/12
1 L = 2 * 12
L = 24 ft
To determine the minimum horizontal length a 2-foot high ramp can have, we need to use the formula for slope: slope = rise / run. The rise in this case is 2 feet. According to the Americans with Disabilities Act (ADA), the slope of the wheelchair ramp should be no greater than 1/12.
Let's plug in the values into the slope formula:
slope = rise / run
1/12 = 2 / run
Now, let's solve for the run (horizontal length):
Cross-multiplying, we get:
1 * run = 12 * 2
run = 24 feet
Therefore, the minimum horizontal length a 2-foot high ramp can have, according to the ADA requirements, is 24 feet.
