Answer and Method

ci A boat can be rowed at 4 km/h. The stream is flowing at 3 km/h towards the east. If the rower rows towards the north, in what direction and at what speed will the boat move? (Find the resultant velocity and direction.) (b If the rower wishes to arrive at a point due north of the launching place, in what direction must the boat be rowed? What will be the speed of the boat in the water? If the distance across the stream is 150m, how long will the crossing take? A stronger rower can move the boat up to 5 km/h. To reach the same place due north, in what direction must the boat now be steered, and what time will the crossing take
