On the map of 1:5000000, the distance between a and B is 6cm. How much should we draw it on the map of 1:3000000

On the map of 1:5000000, the distance between a and B is 6cm. How much should we draw it on the map of 1:3000000

1. Actual distance: 6 △ 1 / 5000000 = 30000000 (CM)
2. Distance: 30000000 × 1 / 3000000 = 10 (CM)

The distance between a and B is 15cm. If the scale of 1:5000000 is used, the distance between a and B is 15cm
It's () meters away

Actual distance between a and B: 3000000 × 15 = 45000000 (CM)
If the scale of 1:5000000 is used, the distance on the map measured by a and B is 4500000 △ 5000000 = 9 (CM) = 0.09m

On the map with a line scale of 0.204060km, the distance between a and B is measured to be 2.5cm. How many kilometers is the actual distance between a and B?
Answer in proportion

Suppose the distance between the two places is actually x km, then 1:20 = 2.5: X
X = 20 × 2.5 = 50 km
The distance between the two places is actually 50 kilometers

On the map with a scale of 1:2000000, the distance between a and B is 2.5cm. How many kilometers is the actual distance between a and B?

Actual distance = 2.5 × 2000000 = 5000000cm = 50km
The actual distance between a and B is 50 km
