Minimizing time Hannah is standing on the edge of an island, 1 mile from a straight shoreline (see figure) She wants to return to her beach house that is 2 miles from the point P on shore that is closest to where she is standing. Given that she can swim at 2 mi/hr and jog at 6 mi/hr, find the point at which she should come ashore to minimize the total time of her trip. If she starts swimming at noon, can she make it home before 1 p.m.?
