Suppose a river is flowing east at 6.00 km/h and a boat is travelling on the river 50.0 degrees south of east with respect to Earth. If the boat’s heading in the water is 65.0 degrees south of east, and the boat’s speed with respect to the river is 17.8 km/h, find the speed of the boat with respect to the Earth. answer choices 21.0 km/h 16.7 km/h 13.6 km/h 22.9 km/h

In an attempt to escape his island, Gilligan builds a raft and sets to sea. The wind shifts a great deal during the day, and he is blown along the following straight lines: 2.50 km 45.0° north of west; then 4.20 km 60.0° south of east; then 1.50 km 25.0° south of west; then 5.30 km straight east; then 1.90 km 5.00° east of north; then 7.20 km 55.0° south of west; and finally 2.90 km 10.0° north of east. What is his final position relative to the island? (i.e., find the magnitude and direction of the displacement.) km at degrees South of East

Gabby works as an aerial photographer. On one trip she takes off from the airport and flies 52km on a bearing N46°E. She then turns and flies for 43km until she is due east of the airport. How far is Gabby from the airport when she is due east of it? Is there more than one answer, explain.
A ship sets out to sail to a point 142 km due north. An unexpected storm blows the ship to a point 130 km due east of its starting point. (a) How far and (b) in what direction (as an angle from due east, where north of east is a positive angle) must it now sail to reach its original destination?
A hiking girl needs to go 59.3 km straight North to get to base camp, instead the compass confuses her and she travels 33.208 km at a 4.9° deflection East from straight North. Then she realizes what she has done and so guesses an angle of 18.4° deflection West of straight North and then hikes 46.254 km. What is the magnitude of her displacement from where she is now located to base camp. (put your answer is standard units)
