Addition of velocities (motion in 2-d).

A boat heads directly across a river 41 m wide at 3.8 m/s. The current is flowing at 2.2 m/s.
1. What is the resultant velocity of the boat?
2. How much time does it take the boat to cross the river?
3. How far downstream is the boat when it reaches the other side?
