Two boats start together and race across a 44 km wide lake and back. Boat A goes across at 44 km/h and returns at 44 km/h. Boat B goes across at 22 km/h, and its crew, realizing how far behind it is getting, returns at 66 km/h. Turnaround times are negligible, and the boat that completes the round-trip first wins.(a) Which boat wins? (Or is it a tie?)
