1. The problem statement, all variables and given/known data A river is 2 km wide and flows at 6 km/h. A motor boat that has a speed of 20 km/h in still water heads out from one bank perpendicular to the current. A marina lies directly across the river on the opposite bank. Use Geometric Vectors to solve this problem. a. How far downstream from the marina will the boat reach the other bank? (Answer: 0.6 km) b. How long will it take? (Answer: 6 min) 2. Relevant equations The sine and cosine laws. 3. The attempt at a solution Here's what I've done so far, I drew the diagram to the problem. I'm not sure if it's correct or not: And now, I don't know what to do to answer the questions.
