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 need to determine the angle at which the man should swim to reach the point directly opposite his starting point and then calculate the time it will take him to cross the river.

### Step 1: Understand the scenario
- The man swims at a speed of 3 km/h in still water.
- The river flows at a speed of 2 km/h.
- The width of the river is 500 meters (0.5 km).

### Step 2: Set up the components of motion
