1. The problem statement, all variables and given/known data Two boats start together and race across a 70-km-wide lake and back. Boat A goes across at 70 km/h and returns at 70 km/h. Boat B goes across at 35 km/h, and its crew, realizing how far behind it is getting, returns at 105 km/h. Turnaround times are negligible, and the boat that completes the round trip first wins. Boat A wins but by how much? 3. The attempt at a solution So I entered into a velocity calculator to determine that it would take Boat A 2hours to finish the course while it would take Boat B 2hrs 40 min to complete the course or simply put boat A wins by 40min 70kmh at 40 minutes would travel 46.667km and yet when I enter the answer for my online homework thingy it says it wrong even when I enter it as 46, 46.6,46.66, and 46.667 What am I missing hear?
