A 1 -inch rise for a 16 -inch run makes it easier for the wheelchair rider to ascend a ramp. How long must a ramp be to easily accommodate a 24 -inch rise to the door?

Let x be the length needed. 16/1 = x/24 x = 384 in

1/16 = x/24 x = 1.5

rise = 24 slope = rise/run = 1/16 24/run = 1/16 run = 24×16 = 384

Hint: Draw diagram tan(θ)=1/16 and sin(θ) = 24/x solve for x

24*16= 384 inches= 32 feet
