1 foot = 0.000189 mile
31,680 feet = 6 miles
Both are correct nice job
Answer: 1/2
<u>Multiply</u>
2×5=10
10/4-2 is your new problem
<u>Simplify</u>
10/4 = 5/2
5/2-2 is your new problem
<u>Subtract</u>
5/2-2=1/2
If a line's slope is

, the slope of the perpendicular line is

in this case, the given line has a slope 4, which is 4/1, so the perpendicular line has a slope/gradient
