Hi, can anyone explain to me in detail the logic/physics to this question? I posted it in general physics, & i guess it's the wrong forum. So i'll post my question here: A riverboat is trying to go north and cross a horizontal river to the other side. In the river, there is a current blowing to the east. Which path should the boat take so that it will arrive at the other end of the river in the shortest time? a)North b)Northeast c)Northwest See diagram for more detail: __________________________________________________ current---> North? Northwest? Northeast? / \ ________________[__ ]<Boat_________________________ Again, please provide a detailed explanation with an answer as well. Thnx!
