The shoreline of Circle Lake is a circle with diameter 2 mi . Nancy’s training routine begins at point E on the eastern shore of the lake. She jogs along the north shore to a point P and then swims the straight line distance, if any, from P to point W diametrically opposite E (Figure Ex-57). Nancy swims at a rate of 2 mi/h and jogs at 8 mi/h . How far should Nancy jog in order to complete her training routine in (a) the least amount of time (b) the greatest amount of time?
