Question

On a 1200 foot stretch of highway through the mountains the road rises by a total of 40 feet find the slope of the road

Answer 1

Remember that

The formula to calculate the slope is

slope=rise/run

In this problem

rise=40 feet (vertical distance)

run=1,200 feet (horizontal distance)

so

slope=40/1,200

slope=4/120

simplify

slope=1/30
