On the map of 1:1000000 scale, the distance between a and B is 2.5cm, then the actual distance between a and B is______ Kilometers

On the map of 1:1000000 scale, the distance between a and B is 2.5cm, then the actual distance between a and B is______ Kilometers

According to the scale = distance on the map: actual distance, the actual distance between a and B is 2.5 × 1000000 = 2500000 (CM) = 25 (km)
