If the distance between a and B is 5cm on the map with the scale of 1:2000, the actual distance between a and B is () A. 10mB. 25mC. 100mD. 10000m

If the distance between a and B is 5cm on the map with the scale of 1:2000, the actual distance between a and B is () A. 10mB. 25mC. 100mD. 10000m

Let the actual distance between a and B be XM. According to the meaning of the question, we get 12000 = 5x · 100, and the solution is x = 100. So the actual distance between a and B is 100m
