A swimmer tries to cross a river swimming at the angle 0 to the perpendicular to the stream (to the left). The speed of the swimmer is v', the speed of the river u (to the right) is unknown, and the width of the river is h. The swimmer lands at the distance d to the right from the opposite point at the other side of the river. What was the speed of the river?

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day, and she is blown along the following straight lines: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 130 km and 25.0 of west, then 5.10 km due east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use the analytical method to find the resultant vector of all her displacement vectors. What is its magnitude and direction?
