How long is the segment representing the distance of 45 km on the map, if the scale of the map is 1: 1,000,000?

With a map scale of 1: 1,000,000, 1,000,000 centimeters of real distance are placed in 1 centimeter of the map.

To solve it, you should determine the total number of kilometers that fit in 1 cm of the map.

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

1,000,000 / 1,000 / 100 = 10 km.

It follows from the calculations that in 1 cm of the map there is a real distance of 10 km.

In this case, the distance on the ground equal to 45 km will be shown on the map as a segment with a length of 45/10 = 4.5 cm.
