6) A plane leaves the airport on the bearing of 45° traveling at 400 mph. The wind is blowing at
a bearing of 135° at a speed of 40 mph. What is the actual velocity of the plane?
7) A ship leaves port on a bearing of 28° and travels 7.5 miles. The ship then turns due east and
travels 4.1 miles. How far is the ship from port and what is its bearing?
8) In order to get across a river to a dock on time, a boat would have to row 65° upstream at
80km/hr if no current was present. If the current is 25 km/hr, what velocity and direction must the
boat travel?
