Answer:
Explanation:
I'm going to have to assume that the 19 ft dimension in the image is the length of the ramp. If that's true, here's my answer
x = horizontal distance of the ramp shown
19² = 3² + x²
x² = 361 - 9 = 352
x = √352 = 18.76
18.76/3 = 6.25/1 ≠ 7/1
So, NO, the ramp shown does not meet the 7:1 recommendation.
To meet the specifications, the horizontal distance has to be:
7/1 = x/3
x = 21 ft
21/3 = 7/1
