1. The problem statement, all variables and given/known data A swimmer who can swim at a speed of 0.80m/s in still water heads directly across a river 86m wide. The swimmer lands at a position on the far bank 54m downstream from the starting point. Determine a) the speed of the current 2. Relevant equations Given : speed of swimmer relative to water = 0.80 m/s 3. The attempt at a solution I'm not really sure how to approach this, since I've been given displacements and not velocities. How do I approach a question like this?
