The scale of a map is given as 1:30000000. Two cities are 4 cm apart on the map. Find the actual distance between them.
Given:
The scale of a map is given as 1:30000000. Two cities are 4 cm apart on the map.
To do:
We have to find the actual distance between the cities.
Solution:
The given scale is 1:3000000.
This implies, 1 cm on the map = 30000000 cm in real.
$3000000\ cm = \frac{30000000}{100}\ m=300000\ m$
$300000\ m = \frac{300000}{1000}\ km=300\ km$
Therefore,
The distance between the two cities $=4\times300\ km=1200\ km$.
