Answer:
0.41 cm
Step-by-step explanation:
The scale on the map is 1 in 86 mi. 
This means that, 1 cm on the map represents 86 miles in real life, or on earth. 
Then we're told that in real life, a distance is 35 miles, and how far they are on the map. 
If 1 cm equals 86 miles, then we can say that x cm equals 35 miles
1 cm ----> 86
x cm ----> 35
x * 86 = 35 * 1
x = 35 / 86
x = 0.41 cm
Therefore, they must be 0.41 cm farther or closer apart on the map scale.
