From a base elevation of 9600 ft. it rises to a summit elevation of 14,255 ft. From the base to the peak the horizontal distance is 15,840 ft. Find the grade expressed as a percentage rounded to nearest tenth


change in elevation = summit elevation - base elevation
change = 14255 - 9600 = 4655 ft
horizontal distance = 15,840 ft
% slope = change in elevation / horizontal distance * 100
grade = % slope = 4655/15840 * 100 = 29.4 % rounded to nearest tenth
