Question: is A--B--C > 11 miles

(1) Two roads from A to B are at least 5 miles long: No information about C. Insuff.
(2) Three roads from B to C are at least 5 miles long: No Information about A. Insuff.

(1) & (2) together,

distance between A & B ≥ 5 miles
distance between B & C ≥ 5 miles

Hence, distance between A & C ≥ 10 miles

So, A to C can be minimum 10 miles and maximum anything. Hence, Insuff.
Ans: E.
