Question

the scale of a map is given as 1:30000000.Two cities are 4cm apart on the map.Find the actual distance between them.

Answer 1

The interpretation of the scale is 1 cm : 30000000 cm
hence the actual distance is 30000000*4 =
120000000 cm = 1200 km

Answer 2

The scale of a map = 1:30000000

two cities are 4cm apart on the map

Distance between them = 4cm × 30000000 = 120000000cm

120000000 cm = 1200 km

So distance between the cities is 1200km
