Q2. Two boats start together and race across a 56-km-wide lake and back. Boat A goes across at 52 km/h and returns at 56 km/h. Boat B goes across at 36 km/h, and its crew, realizing how far behind it is getting, returns at 79 km/h. Turnaround times are negligible, and boat that completes the round-trip first wins.
