You are trying to cross a river. You are able to swim with a speed of 15 m/s with respect to the water. If you are angled at 25 degrees to the left but still make it straight across, what must be the current of the river? If the river is 35m across, how long does it take to get to the other side?

    You attempt to swim across a river 120 meters wide, and can swim at 2.6 m/s in still water. You set off aiming to arrive a point 50 meters downstream of your starting point. However, you fail to take into account the flow of the water, and because of this you land on the opposite bank 100 meters downstream of your starting point. What is the speed of the flow of water, in m/s?

    You want to swim straight across a river that is 76 m wide. You find that you can do this if you swim at an angle of θ = 28° from the upstream direction at a constant rate of 1.5 m/s relative to the water. At what rate does the river flow? The angle θ is measured from the river bank (directly upstream is θ = 0° while directly across the river is θ = 90°).
