Question

a road rises 16 feet for every 50 feet of horizontal distance covered. in percent what is the grade of the road?

Answer 1

32%

Explanation:

The slope of the road is measured as

slope =
`(rise)/(run)` =
`(16)/(50)`

To express as a percentage multiply the fraction y 100% , that is

slope =
`(16)/(50)` × 100% = 16 × 2 = 32%
