Why would a scale be helpful when trying to determine distance an a phiscical map?

A scale on a physical map provides a reference that allows users to convert measurements on the map into real-world distances. By using the scale, one can accurately gauge how far apart locations are, which is essential for navigation and planning trips. Additionally, it helps in understanding the relative size and layout of geographical features, enhancing the overall comprehension of the area being represented. Without a scale, estimating distances could lead to significant inaccuracies.
