If the distance between two places on a map is 2cm while the distance on land is 4km, the scale of the map is?

If the distance between two places on a map is 2cm while the distance on land is 4km, the scale of the map is 1: 200 000. The scale of a map is the relationship between the distance on the map and the actual distance on the ground. It is usually expressed as a ratio, such as 1:50,000 or 1:100,000. In this case, we can use the fact that the distance on the map is 2cm and the distance on the ground is 4km to determine the scale. To do this, we need to convert the distance on the map to kilometers, since the distance on the ground is given in kilometers. If 2cm on the map represents 4km on the ground, then 1cm on the map represents 2km on the ground (since 4km is twice as long as 2km). Therefore, the scale of the map is 1cm to 2km, which can be expressed as a ratio of 1:200,000 (since 1cm is 1/200,000 of 200,000cm, which equals 2km).
