Em um mapa no qual a escala é de 1:200.000, a distância em linha reta entre duas cidades é de 5 cm. Qual a distância real entre essas cidades?

On a map where the scale is 1: 200,000, the straight-line distance between two cities is 5 cm. What is the real distance between these cities?

10km

Explanation:

A scale compares the actual distance on ground to the map distance in use. They help production of maps to be made easier and interpreted better. Anything can fit on a map with the idea of a scale.

Now the map scale is given as:

            1: 200,000

Map distance is 5cm

The given map scale is read as:

  For every 1 unit on the map, we have 200,000 unit on land:

         1cm on the map is 200000cm on the ground;

         5cm on the map = 5 x 200000 = 1000000cm on ground.

The real distance between the cities is 1000000cm;

      This is equal to 10km on ground

the only other powers were germany russia and uk and they were too busy fighting each other wearing each other down   that the us was becoming strong and they were becoming weaker
