1. The airspeed of a plane is km/h and the pilot keeps the plane pointed north. A wind is blowing km/h from the west. Determine the speed (in km/h) of the plane relative to the ground.

2. How many degrees east of north is the airplane in the previous question traveling relative to the ground?

3. The airspeed of a plane is km/h and the pilot keeps the plane pointed [N ºE]. A wind is blowing km/h from the west. Determine the speed (in km/h) of the plane relative to the ground.

4. For the plane in the above question, how many degrees east of north is the plane's velocity relative to the ground?

5. A swimmer can swim at a speed of m/s in still water. If the current in a river m wide is m/s [E], and the swimmer starts on the south bank and swims so that she is always headed directly across the river, how many meters downstream will she land (from the point opposite her starting point).
