Question 145146
A "grade" of a mountain is the same as the "slope".
Slope is defined as "rise" divided by "run".
"Rise" is how high up the peak is relative to the base.  Therefore:
rise = 14767 - 7600 = 7167 feet
run = 15849 feet

So:
slope = rise/run = 7167/15849 = .452
Then to convert to grade multiply by 100
grade = slope x 100 = 45.2%
