Answer to Question #255870 in Geometry for CANDI

Question

A survey worker uses a 4.5 ft stand to site a spot on a road that is 65 feet away. What is the grade of the road? Round your answer to the nearest whole percent.

Answer 1

As we know that:

grade = $\cfrac{rise}{run} 100$

grade = $\cfrac{4.5}{65} \times(100)\\$

$=\frac{450}{65}$

Grade = 6.92%
