Two boats start together and race across a 64 km wide lake and back. Boat A goes across at 64 km/h and returns at 64 km/h. Boat B goes across at 32 km/h, and its crew, realizing how far behind it is getting, returns at 96 km/h. Turnaround times are negligible, and the boat that completes the round-trip first wins.
