Question

What is the slope (grade) of a road that rises 6 feet for every horizontal change of 100 feet ?

Answer 1

3/50

.....,....,.............

Answer 2

`(3)/(50)`

Explanation:

The slope refers to the inclination of the road.

To find the slope, we just have to divide the vertical distance by the horizontal distance, as follows

`m=(\Delta y)/(\Delta x)=(6ft)/(100ft)=(3)/(50)`

Therefore, the slope of the road is
`(3)/(50)`, which means for every vertical displacement of 3 feet, the horizontal displacement is 50 feet.
