Explanation Given Information: The points X and Y are 4 , 000 m apart in the contour map of Mount St. Helens in Washington where all contour lines are in meters. Formula used: The grade is calculated with the help of the following formula: grade = change in elevation distance between two points Calculation: Consider the distance between the points X and Y , 4 , 000 m. Determine the elevation of point X. Since point X, lies on the contour line with length 1 , 750 meters, therefore the elevation of point X is 1 , 750 m
