Answer:
35km
Step-by-step explanation:
Given: The scale of a map is 1:1,000,000
To Find: the real distances between two points if the distance between them on this map is 35mm
Solution:
Distance between two points on map

Scale of map
Therefore,
If distance between two points on map is
real distance is

Distance between two points on map 
Real Distance 

Converting into kilometers,
Real Distance 
if the distance between two points on this map is
, real distance between them is
