In land navigation, what does a bar scale help you determine?

A bar scale, often found on maps, is a graphic representation that helps you visually gauge distances between two points on the map. By using the bar scale, you can align it with the distance you wish to measure, allowing you to interpret the map's scale and convert the distance on the map to a real-world distance. This is particularly useful in land navigation, as it allows you to estimate how far you need to travel from one location to another, ensuring that your navigation is accurate and efficient.

The scale is crucial since every map has its own scale, which may differ significantly based on the map's purpose and area covered. By understanding how to use a bar scale, you can effectively plan routes and estimate travel times based on distance, which is a fundamental skill in land navigation.
