An aircraft flies at a speed v from city A to city B and back in time $$t_0$$. City B is to the east of city A at a distance d. The aircraft takes time $$t_1$$ for the round trip if wind blows with speed w along AB and time $$t_2$$ if the wind blows with the same speed perpendicular to AB. Then,

A

$$t_1 = t_2 = t_0$$

B

$$t_1 > t_2 > t_0$$

C

$$t_1 < t_2 < t_0$$

D

$$t_1 > t_0 > t_2$$
