Jon is attempting to swim straight across a swift flowing river that is 30 meters wide. Jon can swim at 5 m/s relative to the water. The current is moving at 7 m/s and Jon makes no correction for the current. How far downstream does Jon end up by the time he reaches the other shore?
how much time does it take to swim across?
How far downstream? distance=currentspeed*time
