How many kilometres on the ground is 3 cm distance on the map of south africa

Answer 1

That depends upon the map you're seeing.

Answer 2

As Ms Sue said, it depends on the scale on your map

Usually at the bottom of your map you will see something like this

1 : 100 000

What that means is that for each unit on the map you would have 100 000 of the same units in real life
e.g for the above scale
1 cm on the map would be
100 000 cm in reality
= 1000 m
= 1 km

so for a scale of 1 : 100000
1 cm ---> 1 km

Answer 3

The distance on ground between two places that are 7cm apart on the south africa
