Question: 3 . A swimmer needs to swim from a point on the beach to a floating platform 5 0 m directly across from the shore.

3. A swimmer needs to swim from a point on the beach to a floating platform 50 m directly across from the shore. They can swim at a speed of \(4\mathrm{~km}/\mathrm{h}\) in calm water. The lake has a \(2\mathrm{~km}/\mathrm{h}\) current that runs parallel to the shore. If they want to swim straight across to the dock, at what angle should they aim themself upstream before they start swimming? Draw a diagram of the situation. [4 marks]
