Question: You are going to go across Mississippi river from East to West bank by rowing your kayak. You know you can row 3 m/s in still water. You discovered that river flows with a water speed of 2 m/s from North to South.
Part A: What direction you should aim at in order to go across the river in the shortest time?
I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
