find run of 4'-8" rise and slope12.5%

Question

rise 56 inch slope 12.5% find run in ft. / in. you can use 1 unit rise to 8 unit run too.

Answer 1

kall a slope=such & such % is old fashuned

Bak in 1800's, em bild rodes that wae...eezee tu du with primitiv equipment

It spozed tu meen the rise=x% av the horizontal distans (the run)

In praktis, em alwaes yuze the distans along the rode insted av the run

Reesunabel rodes limited tu bout 8%, so dont get much errer that wae

But 12.5% slope is rather big

run=4ft 8 inch =56 inch,

rise=12.5% av run =0.125*56=7 inch
