Using the information given, calculate a grade to the nearest whole percent. The "rise" is 525 feet. If the scale on the map sho
melamori03 [73]
The grade on the west side would be the vertical rise divided by the horizontal run or 525 divided by 800' or rounded off to 66% (a steep grade as in an underground mine a grade of 25% is considered very steep for vehicles to go up or conveyors to travel). On the east side the 40% grade was obtained by dividing the 525' vertical height by the 1300' run.
