8These darn homing pigeons! I can not get my calculations correct. where is the mistake in my calculation?

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 16 mi downshore from the pigeon's home loft at point A. Assume that a pigeon flying over water uses energy at a rate 1.21 times the rate over land. Toward what point 5 downsshore from A should the pigeon fly in order to minimize the total energy required to get to the home lot at A? 16-1 Total energy - (Energy rate over water) . (Distance over water) + (Energy rate over land) . (Distance over land) Point S is 14.31 miles away from point A (Type an integer or decimal rounded to three decimal places as needed )
