The path traveled by the traveler on a map of scale 1: 25,000,000 is 4 cm.

The path traveled by the traveler on a map of scale 1: 25,000,000 is 4 cm. Calculate how much of the distance from the equator to the North Pole is the path traveled by the traveler.

To solve this problem, you first need to convert the specified map scale from centimeters to kilometers.

Since 1 km – 1000 meters, and 1 meter – 100 cm, the scale of the map will be equal to:

25,000,000 / (1,000 * 100) = 25,000,000 / 100,000 = 250 km.

There are 250 km in 1 centimeter of the map.

Since the distance traveled by the traveler on the map is 4 cm, it means that he has overcome everything:

250 * 4 = 1000 km.

The distance between the Equator and the North Pole is 10,000 km, so he walked:

1000/10000 = 1/10 part.

Answer: 1/10 part or 10%.
