On a map, half centimeter shows 125 kilometres on the ground. If two cities are actually 2000 kms apart on the ground, then the distance between them on the map is:

Correct option is C

First, let's find the scale of the map:
0.5 cm on the map represents 125 km on the ground.
So, 1 cm on the map represents 125 km / 0.5 cm = 250 km on the ground.
Now, let's find the distance between the two cities on the map:
If 250 km on the ground is represented by 1 cm on the map, then 2000 km on the ground will be represented by:
2000 km / 250 km/cm = 8 cm
Therefore, the distance between the two cities on the map is 8 cm.
So, the correct answer is (c) 8 cm.
