Answer is A (15).
Total cities = 6
Total entries = 6*6 = 36
Entries in same cities (A and A, B and B and so) = 6
Entries left = 36-6 = 30
Every entry repeated twice (e.g. A and B = B and A) = 30/2 = 15
So the answer is 15.

Thinking logically will allow you to find the answer.........since the answer asks for the minimum b/tw cities you need only account for the mileage once. Start at the top left corner, one down, and then follow diagonally down the line.....all blocks below will count, the number should add up to 15
not sure this is coherent.....
