Question

the americans with disabilities act (ada) requires, among other things, that wheelchair service ramps have a slope not exceeding 1/12. (a) suppose the front steps of a building are 2 feet high. you want to make a ramp conforming to ada standards that reaches from the ground to the top of the steps. how far away from the building is the base of the ramp? incorrect: your answer is incorrect.(b) another way to give specifications on a ramp is to give allowable inches of rise per foot of run. in these terms, how many inches of rise does the ada requirement allow in 1 foot of run?

Answer 1

The base of the ramp should be placed 24 feet away from the building. The ADA requirement allows for a rise of 1 inch per foot of run.

Step-by-step explanation:

The base of the ramp should be placed at a distance from the building that allows for a slope not exceeding 1/12. To calculate the distance, we can use the formula:

Distance = Height of steps x 12

Plugging in the values, we have:

Distance = 2 feet x 12 = 24 feet

Therefore, the base of the ramp should be placed 24 feet away from the building.

Alternatively, in terms of allowable inches of rise per foot of run, the ADA requirement allows for a 1/12 slope. This means that for every foot of horizontal run, the ramp can rise up to 1/12 of a foot. Since there are 12 inches in a foot, the ADA requirement allows for a rise of 1 inch per foot of run.
