Question 468828
On a 3% railroad grade, at what angle are the rails inclined to the horizontal,
tan^-1(3/100) = 1.7184 degrees
---------------------------------

and how far does one rise in traveling upward 5000 feet measured along the rails?
r/5000 = 3/100
r = 5000(3/100)
rise = 150 ft
---------------------------------

================================

 (The track rise 3 feet for each 100 feet of horizontal distance gained.)
