A swimmer is 200 meters from the closest point on a straight shoreline. She needs to reach a cottage located 1500 meters down shore from the closest point. If she swims at m/s and she walks at 2 m/s, how far from 3 the cottage should she come ashore so as to arrive at the cottage in the shortest time? time = distance rate 2. An open box is to be made from a square piece of material, 24 inches on a side, by cutting equal squares from the corners and turning up the sides. What is the maximum volume that can be created?
