A kayaker needs to paddle north across a 100-mm-wide harbor. The tide is going out, creating a tidal current that flows to the east at 2.0 m/sm/s. The kayaker can paddle with a speed of 3.0 m/sm/s. In which direction should he paddle in order to travel straight across the harbor? How long will it take him to cross?
