On a map with a scale of 1 / 2500000, the distance between Tianjin and Beijing is 4.8 cm On a map with a scale of 1 / 2500000, the distance between Tianjin and Beijing is 4.8 cm. How many kilometers is the actual distance between Tianjin and Beijing

The actual distance from Tianjin to Beijing is xcm
1/2500000＝4.8/ x
x＝4.8×2500000
x＝12000000
12000000cm＝120km
A: about 120 km
