Question

Calculate each mountain path grade to the nearest percent. Path A for every 31 meters of horizontal​ distance, the vertical change is 11 meters Path B for every 4.25 meters of horizontal​ distance, the vertical change is 3 meters?

Answer 1

What we must do in this case is to calculate the slope in each route in a percentage way.
 We have then:
 Path A
 m = (11/31) * (100) = 35.48387097%
 m = 36%
 Path B 
 m = (3 / 4.25) * (100) = 70.58823529%
 m = 71%
 Answer: 
 Path A = 36% 
 Path B = 71% 
 Route A is less inclined than route B.
