On a map in scale 1: 1,000,000, the distance between stations is 2.5 cm. What is the distance between stations on the ground?

If the scale of the map is 1: 1,000,000, then 1,000,000 centimeters of real terrain are depicted on one centimeter of the map.

Since there is 2.5 cm between stations on the map, the real distance in centimeters will be equal to:

2.5 * 1,000,000 = 2,500,000 cm.

When converting this value to kilometers. we get:

2500000/100000 = 25 km.

Answer: The distance between the stations is 25 km.
