Mauritius  island  is  2  km  due  south  of  its  closest  point  along  a  straight  coastline. Gibril is staying at a private room on the shore that is 6 km east  of that point. Gibril is planning to go from the room to the island. Suppose  Gibril runs at a rate of 8 kmph and swims at a rate of 3 kmph. How  far  should Gibril run before swimming to minimize the time it takes to reach  the island?
