How to Solve Scale Problems Using Maps1) Measure the distance
between the two cities (for multiple stops, add distances together).
2) Write a proportion using the scale as one of the ratios. Let n or x represent the actual distance.
3) Solve the proportion.

Objective Review • To use maps scales and
proportions to find actual distances.
• Why? To You now know how to read maps and know the distances between cities.
• Since a map is a scale drawing, you can use your knowledge about scale and proportions to find actual distances.
• Be sure to set up your ratios or proportions equally.
