The contour interval of a topographic map is 50 feet. how many contour lines would be drawn between sea level and an elevation of 175 feet?

Option (B)

Explanation:

The contour lines are very important to understand the elevation of a particular location and they are the important features in a topographic map. These contour lines are separated from one another by a fixed amount (value).

In the given condition, the contour interval is 50 feet.

There will be 3 contour lines between the mean sea level and an elevation of 175 feet. These 3 contours will be representing the heights 50 feet (first contour), 100 feet (second contour) and 150 feet (third contour) respectively.

Thus, the correct answer is option (B).

just took the test the answer is b.
