On a map with a scale of 1:300000, the distance between a and B is 12 cm, and the actual distance between them is 12 cm______ If the scale of 1:500000 is used, the distance between a and B should be drawn______ Cm

On a map with a scale of 1:300000, the distance between a and B is 12 cm, and the actual distance between them is 12 cm______ If the scale of 1:500000 is used, the distance between a and B should be drawn______ Cm

(1) 12 △ 1300000 = 3600000 (CM), 3600000 cm = 36km; (2) 3600000 × 1500000 = 7.2 (CM); answer: the actual distance between them is 36km, if the scale of 1:500000 is used, the distance between a and B should be 7.2cm; so the answer is: 36, 7.2
