Pilots use the face of a clock to express bearings. The actual flight direction is identified with 12 o'clock, so, for example, instead of 90 degrees to the right'' they say 3 o'clock'', or behind me'' equals to 6 o'clock''. Follow the flight path of a reconnaissance plane that takes off from the base and flies 3 minutes in a given direction, then turns to 2 o'clock and flies 4 minutes, then turns again to 2 o'clock and flies 3 minutes, finally the plane turns to 4 o'clock and flies 9 minutes. In what clock direction should the plane be turned to in order to fly straight back to the base? How many minutes does this take?
