The map scale is 1 unit on the map corresponds to 1,400 km in reality. This ratio establishes the relationship between distances on the map and actual distances on the Earth's surface.
In a map, the representation of a segment measuring 1,400 km provides information about the map's scale. The scale of a map defines the relationship between the distances on the map and the corresponding distances on the Earth's surface.
To determine the scale, you need to compare the map distance to the actual ground distance it represents. In this case, if the marked segment on the map corresponds to a real-world distance of 1,400 km, you can express the scale as a ratio. The scale ratio is calculated as follows:
![\[ \text{Scale} = \frac{\text{Map Distance}}{\text{Actual Distance}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/9s8qnf8bj2rf6e7683l960m0pzwve71ooz.png)
Substitute the given values:
![\[ \text{Scale} = \frac{\text{1 unit on the map}}{\text{1,400 km in reality}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/o9e3nkixu9mofp37woj8ggcvan5w1wc6e2.png)
Therefore, the scale of the map is 1 unit on the map to 1,400 km in reality. This means that each unit of length on the map represents a distance of 1,400 km in the actual world. Understanding the scale is crucial for accurately interpreting distances on the map and planning real-world journeys or activities.
