What is the exact distance in a real ground denoted by RF 1:1000000 in a map?

1 cm rep 10 km

Explanation:

We are given an RF 1: 1000000

We first need to understand what this means

It means that 1 cm rep 1000000 cm on the ground

Therefore;

1 cm rep 1000000

but, 100000 cm = 1 km

Therefore, we would say

1 cm rep 10 km

Therefore, 1 cm on a map represents 10 km on the ground.

So if we are given 2 cm on the map, that would be 20 km on the ground, 4 cm would be 40 km.
