The diagram below shows the position of a cross-country skier at various times. At each of the indicated times, the skier turns around and reverses the direction of
travel. In other words, the skier moves from A to B to C to D.
Use the diagram to determine
the resulting displacement and the distance traveled by
the skier during these three minutes.
