Find the distance between cities A and B, if the distance between them on the map is 3.4 cm and the scale of the map is 1: 3000000.
Let’s use the proportion to solve the problem of finding the distance between two cities.
Proportion is the equality of two relationships. There is a ratio of the scale of the map and a value that expresses the distance between two cities.
1 cm / 3,000,000 = 3.4 cm / x
x = 3.4 * 3,000,000
x = 10200000
