= time taken to travel the distance with wind
Time taken to travel the distance with wind is given as

eq-1
Consider the motion of the bird with the wind
= distance traveled against the wind = 6060 mi
= time taken to travel the distance against wind
Time taken to travel the distance against wind is given as

eq-2
