You want to get from a point A on the straight shore of the beach to a buoy which is 62 meters out in the water from a point B on the shore. B is 70 meters from you down the shore. If you can swim at a speed of 4 meters per second and run at a speed of 6 meters per second, at what point along the shore, x meters from B, should you stop running and start swimming if you want to reach the buoy in the least time possible? B Buoy T(x) : x = swim Find a formula for the time spent in terms of x = 3844+x² 4 70 - X 70 m 6 run wwww A Find the value for å that will minimize the total time spent running and swimming.
