On a geographical map of scale 1: 90,000,000, the distance from Kiev to Paris is 2.2 cm.

On a geographical map of scale 1: 90,000,000, the distance from Kiev to Paris is 2.2 cm. Calculate the real distance between these cities.

On a map with a scale of 1: 90,000,000, 90,000,000 centimeters of real terrain are displayed in 1 centimeter of the map.

We translate the scale of the map from centimeters to kilometers.

Since 1 km – 1000 meters, and 1 meter – 100 cm, we get:

90,000,000 / (1,000 * 100) = 90,000,000 / 100,000 = 900 km in 1 cm.

We find the real distance.

To do this, we multiply the scale of the map in kilometers by the length of the segment on the map.

In this case, get:

900 * 2.2 = 1980 km.

Answer: The real distance from Kiev to Paris is 1980 km.
