Question

On a topographic map, six contour lines span a horizontal map distance of 0.5 inches. The horizontal scale is 1 inch equals 2,000 ft. How far apart are the first and sixth lines?

Answer 1

1000 ft

Step-by-step explanation:

There are six lines which has a total length of 0.5 inches on the map. This is known as the scale of a map.

On the map we have

`1\ inch=2000\ ft`

So, the distance between first and sixth line is 0.5 inch

`0.5\ inch=0.5* 2000`

`\Rightarrow 0.5\ inch=1000\ ft`

The distance is 1000 ft on the map
