The above rectangle is a channel that in broken into 8 identical square sectors. Boats A and B are at opposite ends of the channel. They begin sailing at the same time, and go back and forth parallel to the shores from one end of the channel to the other. Neither boat varies its speed at any time and the time each boat spends turning around is negligible. In which sector will they pass each other for the second time?

(1) They pass for the first time in sector 7.
(2) They pass for the third time in sector 3.

Consider (1)
Indicates that when A covers 7 blocks, B covers 2 blocks, this is sufficient to say where they will intersect again.
So (1) is sufficient.

Consider (2)
This does not give any information about their relative speeds and is not sufficient.

ANS â€“ (1) Alone is sufficient.

Cheers,
Anand

I think its C.

St1: Two possibilities: 1. Speed of A = 7x, Speed of B = x. 2.Speed of A = 3x, Speed of B = 2x --INSUFF

St2: Same way there are multiple possibilities - : INSUFF

Combined: I did not calculate but I feel that one possibility out of 2, described in st1, will work.
