1. The problem statement, all variables and given/known data A canoist is rowing upstream a river. After 2miles he passes a log (traveling with the current) he continues to row for one more hour and turns around. He reaches his starting point at the same time as the log. What is the rate of the current? 2. Relevant equations 3. The attempt at a solution v1+v2/c To be honest I don't even know where to begin with this problem. The teacher gave it to us as a joke because he said this was something from his highschool book in Russia and hasn't found anyone in the U.S who can solve it.
