Question

What is the slope (grade) of a road that rises 10 feet for every horizontal change of 25 feet?

Answer 1

`m = (2)/(5)`

Explanation:

Slope formula:

`m = (rise)/(run)`

Given:

Rise: 10

Run: 25

Replace with the given information, simplify after

`m = (10)/(25)`

Divide numerator and denominator by 5

`m = (10 / 5)/(25 / 5)`

Answer:

`m = (2)/(5) ft`
