Question

The scale of a map is 1:10,000,000. What is the real distance between two cities if the distance between them on map is 1.7 dm.

Answer 1

Answer:

The two cities are 1,700,000,000 mm or 1700 km away from each other.

Step-by-step explanation: The scale of the given map, 1:10000000 can be interpreted as 1 mm in the map will be 10,000,000 mm in real world.

Again, we know,

1 dm = 100 mm

Thus, 1.7 dm = 170 mm

Hence, if two cities in the map are 170 mm away, then in real life, the cities would be 170 * 10,000,000 mm away from each other.

Thus, the two cities are 1,700,000,000 mm away from each other.

Since, 1 mm = 0.000001 km

Therefore, 1,700,000,000 mm = 1700 km.
