On a map with horizontal distance between points 1 and 2 is 8cm. If the elevations of points 1 and 2 are 10.14 and 19.66, respectively, how far from point 1 will a contour line with an elevation of 14 will cross line 1-2?
By similar triangle,
\[
\frac{19.66-10.14}{8cm.} = \frac{14-10.14}{x}
\]
\[
x = 3.243697478991597cm.
\]
\[
x \approx 3.24cm. \leftarrow \text{answer}
\]
