On some maps, a divided bar shows the scale
of a map.
0
5 10 20 40
miles
From the 0 to the 5 equals 5
miles on the map. From the 0 to the 10 equals 10
miles on the map. From the 0 to the 40 equals 40
miles on the map. You can measure the distance from
one place to another on a map by comparing the
distance to the scale.
Luckily, many maps include
the distances from one place to another, but when
you need to, you can do your own measuring. You can
use a piece of thin string to measure from one place
to another, and then compare your string to the
scale. Try to follow the roads with your
string. Try this method on the following map.
Remember, you will get an estimate, that is, a
quick, but not exact number. Print the map
first. Notice the scale shown on the map to
determine 40 miles or 40 kilometers. For a
very rough estimate, use a ruler to measure from
place to place.
