An airplane flies northward from town A and B and then back again. There is a steady wind blowing towards the north so that for the first state of the trip, the airplane is flying in the same direction as the wind and for the return trip of the journey, the airplane is flying opposite of the wind. The total trip time Tω as compared to the total trip time in the absence of any winds T0 is:
