Question

A hill on a hiking trail goes up to 69 feet over a distance of 138feet. Find the grade of the hill

Answer 1

Answer: The grade of the hill = 50%

Explanation:

The grade is the slope( expressed as a percent). To evaluate the slope we divide the rise by the run.

Given: A hill on a hiking trail goes up to 69 feet over a distance of 138 feet.

So, rise= 69 feet , run = 138 feet.

The grade of the hill =
`(rise)/(run)*100`

`=(69)/(138)*100=50\%`

Hence, the grade of the hill = 50%
