Point H has an elevation of 781.58 ft. Point G has an elevation of 859.08 ft. If the horizontal distance between them is 1300.00 ft. What is the grade expressed as a percentage to two decimal places?

Solution

given elevation at point H is 781.58 ft

horizontal distance =1300ft

grade =[(859.08-781.58)_/(1300)]*100

grade =5.96%
