Question

14 multiple choice 6 points what is the contour interval on the topographic map above? 5 m 10 m 25 m 12.3 m

Explanation:

Step1: Identify known contour values

We have contour values 425 and 450.

Step2: Calculate the difference

The difference between 450 and 425 is $450 - 425= 25$.

Step3: Count the number of contour - lines between them

There are 5 contour - lines (including the 425 and 450 lines themselves) between the 425 and 450 contour lines. But the number of intervals is $5 - 1=4$.

Step4: Calculate the contour interval

The contour interval is $\frac{25}{5}= 5$ (since the difference of 25 is spread over 5 intervals).

Answer:

5 m
