Answer:
see the explanation
Step-by-step explanation:
we know that
The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
[tex]slope=\frac{rise}{run}[/tex]
so
In this problem we have
[tex]rise=30\ ft[/tex]
[tex]run=483\ ft[/tex]
substitute
[tex]slope=\frac{30}{483}[/tex]
simplify
[tex]slope=\frac{10}{161}[/tex]
or
[tex]slope=0.0621[/tex]
Convert to percentage
[tex]slope=0.0621*100=6.21\%[/tex]
