Question 163569: There are 2 boats docked on opposite sides of a river. The sides of the river are parallel and the current is negligible. The 2 boats set out to cross the river at the same time, and each maintains a constant rate. They first meet at 800 yards from side 1, then proceed to the opposite side and turn around. Next they meet 300 yards from side 2. How wide is the river? What happens if 800 yards is replaced with D1 and 300 yards is replaced with D2 if both D1 and D2 are assumed to be less than the width of the river?
