Explanations:Map reading involves understanding the scale of the map, which is a ratio that indicates how distances on the map correspond to actual distances in the real world. The scale is typically given as a ratio, such as 1cm on the map representing 10km in reality. This means that every centimeter on the map represents 10 kilometers in the real world.
In this question, the scale is given as 1cm on the map equals 10km in reality. The distance between Mumbai and Delhi on the map is 60cm. To find the actual distance, we need to multiply the map distance by the scale factor. The calculation is as follows:
Actual distance = Map distance × Scale factor
Substituting the given values:
Actual distance = 60cm × 10km/cm
Actual distance = 600km
Therefore, the actual distance between Mumbai and Delhi is 600km. This corresponds to Option B.
It is important to note that the scale is a ratio and not a direct measurement. This means that the units of measurement must be carefully considered. In this case, the map distance is in centimeters, and the scale factor converts this to kilometers. The units must be consistent and correctly applied to avoid errors in the calculation.
Common mistakes in such problems include forgetting to multiply the map distance by the scale factor, confusing the units of measurement, or misinterpreting the scale as a direct measurement rather than a ratio. Understanding the concept of scale and how to apply it correctly is crucial for accurate map reading and distance calculation.
