A boat heads directly north across a river, 68 m wide at a rate of 3 m/s. The current is flowing downstream (due west) at 1.9 m/s. A. What is the resultant velocity and direction of the boat? Write your angle as a bearing. B. How long does it take the boat to cross the river? (Hint: How long does it take to covert the vertical distance of 68m across the river?) C. How far downstream is the boar when it reaches the other side of the river?
