Convert the real distance into the unit used by the map measurement first.
- Convert the real distance into the unit used by the map measurement first.
- Divide by the scale factor to move from reality back to the map.
- The map distance should be much smaller than the real distance.
Example 1
A map has scale 1 : 50000. Two places are 1.25 km apart in reality. How far apart are they on the map, in cm?
Example 2
A map has scale 1 : 60000. Two places are 1.8 km apart in reality. How far apart are they on the map, in cm?
Remember
Use the worked steps to check your method, not just the final answer.
