If two successive contour lines are 75 feet apart, what's the contour interval for this particular map 30 points!!

BAHASA INDONESIA= jika dua garis kontur berurutan berjarak 75 kaki, berapa interval kontur untuk peta khusus ini

BAHASA INGGRIS= if two successive contour lines are 75 feet apart, what's the contour interval for this particular map.

Divide the difference in elevation between the index lines by the number of contour lines from one index line to the next. In the example above, the distance 200 is divided by the number of lines, 5. The contour interval is equal to 200 / 5 = 40, or 40-unit contour intervals.

Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. The actual contour interval of a map depends upon the topography being represented as well as the scale of the map.

Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. The diagram illustrates how contour lines show relief by joining points of equal elevation.

SORRY IF THERE IS A MISTAKE.
