21.6 inches
2 % grade is 100 along and two up ( same units), so 4" up = 200" along 200" = 16 feet 8 inches horizontally
A 10% grade rises 1 foot for every 10 feet that it proceeds horizontally. This can go on for miles.
31 inches = how many feet and inches 2 feet and 7 inches
However many amounts of 12 there are, that is how many feet, and then the remaining will be how many inches.

2 % grade is 100 along and two up ( same units), so 4" up = 200" along 200" = 16 feet 8 inches horizontally
A 10% grade rises 1 foot for every 10 feet that it proceeds horizontally. This can go on for miles.
It is 2% of 116 ft = 2.32 feet = 2.32*12 = 27.84 inches.
you need to find how many inches the 4 feet are then you multiply that by .04 and you have your answer, 2.4 inches
