On a map with a scale of 1:100000, the distance between a and B is 20cm. If you draw on a map with a scale of 1:50000, how many centimeters should you draw?

Actual distance = 20 × 100000 = 20000000cm = 20km
1：50000
Map distance = 2000000 △ 50000 = 40cm

On a map with a scale of 1:80000, the distance between the two places is 17.5cm, and on another map with a scale of 1:50000
How many centimeters is the distance between the two places

According to: distance on the map: actual distance = scale, we can get 17.5: x = 1:80000, x = 1400000 cm, and then we can get: x = 1:80000
x: 1400000 = 1:50000, x = 28cm
