Question

question image
contour interval: 20 m
q. what is the difference in elevation between point x and point y?

Explanation:

Step1: Determine the elevation of Point X

Point X is on the 1600 - meter contour line. So, the elevation of Point X is \(1600\) m.

Step2: Determine the elevation of Point Y

Point Y is on the 1200 - meter contour line. So, the elevation of Point Y is \(1200\) m.

Step3: Calculate the elevation difference

The formula for elevation difference \(\Delta h\) is \(\Delta h=h_X - h_Y\). Substituting \(h_X = 1600\) m and \(h_Y = 1200\) m, we get \(\Delta h=1600 - 1200\).

Answer:

\(400\) m
