Solve the all parts of given question:

Question: A swimmer, capable of swimming at a speed of 1.2 m/s in still water (i.e., the swimmer can swim with a speed of 1.2 m/s relative to the water), starts to swim directly across a 2.1-km-wide river. However, the current is 0.91 m/s, and it carries the swimmer downstream.

Part A: How long does it take for the swimmer to cross the river?

Part B: How far downstream will the swimmer be upon reaching the other side of the river?

Please keep it short and simple and please no copy and paste.
