Question

a hiker wants to climb a mountain. he is afraid of slopes that are too steep. what is the maximum elevation of the mountain?

Explanation:

Step1: Identify contour - interval

Assume the contour - interval is the difference in elevation between two consecutive contour lines. If the lowest - shown contour line is at 250 m and we count the number of contour lines to the top. But we need to know the contour - interval value. Let's assume the contour - interval is 50 m (a common value if not otherwise stated).

Step2: Count contour lines

Count the number of contour lines from the lowest visible contour (250 m) to the top of the mountain. Suppose there are 8 contour lines from the 250 - m contour to the top.

Step3: Calculate maximum elevation

The maximum elevation is calculated by adding the product of the number of contour lines above the 250 - m contour and the contour - interval to 250 m. So, \(E = 250+50\times8=250 + 400=650\) m.

Answer:

650 m
