On a map with a scale of 1:300000, the distance between a and B is 5.5cm. If it is changed to a map with a scale of 1:500000, the distance between a and B is 5.5cm fast

On a map with a scale of 1:300000, the distance between a and B is 5.5cm. If it is changed to a map with a scale of 1:500000, the distance between a and B is 5.5cm fast

The actual distance between a and B is:
5.5 ÷ (1 / 300000) = 1650000 cm
1650000 × 1 / 500000 = 3.3cm
A: if it should be a 1:500000 map, the distance between a and B is 3.3cm
