Air Race from Metropolis to Aniba Gothic and Back

[leprofece]

3.82 in an air race, an aircraft flies from a point directly above Metropolis to a point directly city aniba Gothic, turn and return at starting point. The speed of the aircraft with respect to the air is constant in all the flight and equal to v. city is Gothic a distance D to the East of Metropolis. (Cuanto tiempo se requiere si sepla un viento con rapidez constante w b) to the East? (c) towards the South?

Answer b) \frac{2Dv}{v^2-w^2} I have no idea of this answer It should be 2d/v-w

c) \frac{2d}{\sqrt{v^2-w^2}}}
