Q. Two boats start together and race across a 56km wide lake and back. Boat A goes across at 56 km/h and returns at 56km/h. Boat B goes across at 28km/h, and its crew, realize how far behind it is getting, returns at 84km/h. Turnaround times are negligible, and boat that completes round-trip first wins.

Which boat wins and by how much?
