Homing pigeons avoid flying over water. Suppose a homing pigeon is released on an island at point​ C, which is 7 mi directly out in the water from a point B on shore. Point B is 16mi downshore from the​ pigeon's home loft at point A. Assume that a pigeon flying over water uses energy at a rate 1.22 times the rate over land. Toward what point S downshore from A should the pigeon fly in order to minimize the total energy required to get to the home loft at​ A?
