1. The problem statement, all variables and given/known data A fisherman wishes to cross a river to the shore directly south of his position. The river is 400 m across, and the fisherman's boat is capable of a speed of 2.5m/s. If the river's current has a velocity of 1.5m/s [W], determine a) the time it takes the fisherman to cross the river (200 s) how far downstream he will be before he reaches the other shore (300 m) This is the part I didn't answer. If the fisherman wished to land on the shore directly south of his position, how long would it him take to cross the river, and what would be the ground velocity of the boat? 2. Relevant equations d =v*t 3. The attempt at a solution I have calculated the time from question 1, but I'm not sure what is different about time in question 2. I was thinking the ground velocity is 2 m/s since it would be d/t.
