Answer 2

Problem 1: Distance between two villages on a map

The scale of the map is 1:1,000,000, and the distance between the two villages on the map is 8 cm. We need to determine the actual distance between these villages on the ground.

To find the actual distance, we can use the scale of the map. The scale 1:1,000,000 means that 1 cm on the map represents 1,000,000 cm (or 10,000 meters) on the ground.

Using this information, we can calculate the actual distance between the two villages:

8 cm on the map * 1,000,000 cm (10,000 meters) on the ground = 8,000,000 cm (or 80,000 meters)

Therefore, the actual distance between the two villages on the ground is 80,000 meters.

Problem 2: Distance between two cities on a map

The scale of the map is 1:2,000,000, and the distance between the two cities is 100 km. We need to determine the distance between these cities on the map.

To find the distance on the map, we can use the scale of the map. The scale 1:2,000,000 means that 1 cm on the map represents 2,000,000 cm (or 20,000 meters) on the ground.

Using this information, we can calculate the distance between the two cities on the map:

100 km on the ground * 1 cm on the map / 20,000 meters on the ground = 0.005 cm on the map

Therefore, the distance between the two cities on the map is 0.005 cm.

Problem 3: Determining the scale of a map

The distance between cities A and B is 140 km, and the distance between cities A and B on the map is 7 cm. We need to determine the scale of the map.

To find the scale of the map, we can use the given distances. The scale of a map is the ratio of the distance on the map to the corresponding distance on the ground.

Using this information, we can calculate the scale of the map:

140 km on the ground / 7 cm on the map = 20 km/cm

Therefore, the scale of the map is 1:20,000 (1 cm on the map represents 20,000 cm or 200 meters on the ground).
