A section of a topographic map is shown below. What is the difference in elevation in meters between Point X and Point Y on the

The elevation difference between points X and Y is 360 meters. The map visually illustrates elevation through contour lines, which are labeled with their respective heights, with major contour lines displayed every fifth interval. The contour interval stands at 20 meters, which aids in determining elevation differences between locations on the map. We discern from the map that the elevation increases from southeast to northwest, where the difference between each contour line is 20 m, and the gap between main contour lines is 100 m. Point X is shown on the contour line of 1,600 m, while point Y is located between the 1,200 m and 1,300 m contour lines, specifically at 1,240 m, calculated as 2 x 20 = 40 m. Thus, from the two points, the elevation difference is 1,600 - 1,240 = 360 m.
