A boat is to cross a river on a course directed 20.0° north of east in 10 minutes from point A to point B. The distance from point A to point B is 815m. If the river flows at a speed of 3.0 km/hr, at what angle upstream must the boat be headed, and what must be its speed in km/hr relative to the moving water?
