Answer:
25m
Explanation:
A contour line is a line that joins places of equal elevation values on a map. As a rule, contour lines do not cross one another.
A contour interval is the difference between two close contours. This interval is used to construct the contour lines of a given map.
In this map;
Change in elevation = 300 - 200 = 100
Now, we have 4 contours between the 200 and 300 contour lines.
Therefore, contour interval is;
Contour interval = [tex]\frac{100}{4}[/tex] = 25m
