A man can swim in still water ast a speed of 3 km/h. He wants to cross a river that flows at 2 km/h and reach the point directly oposite to his starting point. A. In which diretionshoeld he try to swim (that is, find the angle his body makes wilth the river flow)? b. How much time will he take to cross the river if the river is 500 m wide?

Explanation

To solve the problem step by step, we will break it down into two parts: finding the angle at which the man should swim and calculating the time taken to cross the river.

### Part A: Finding the Angle

1. **Identify the Given Data:**
- Speed of the man in still water, \( V_m = 3 \) km/h
- Speed of the river, \( V_r = 2 \) km/h
