Answer:
The grade of a slope is [tex]16.7\%[/tex]
Step-by-step explanation:
we know thatThe formula to calculate the slope is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
where
[tex]{y2-y1}=400\ ft[/tex] -----> is the rise
[tex]{x2-x1}=2,400\ ft[/tex] -----> is the run
substitute
[tex]m=\frac{400}{2,400}=0.167[/tex]
Convert to percentage
[tex]0.167*100=16.7\%[/tex]
answer:
the grade of a slope with a rise of 400 feet and a run of 2400 feet is
16.7%
