$\huge\boxed{\fcolorbox{black}{pink}{Answer}}$

The map scale is ratio between the map distance and the ground distance.

Answer 2

Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.
