Solve the all parts of given question:
Question: A swimmer, capable of swimming at a speed of 1.85 m/s in still water (i.e., the swimmer can swim with a speed of 1.85 m/s relative to the water), starts to swim directly across a 1.14-km-wide river. However, the current is 1.04 m/s, and it carries the swimmer downstream.
Part A: How long does it take the swimmer to cross the river?
Part B: How far downstream will the swimmer be upon reaching the other side of the river?
