An airplane fies nontwird fram town town Band then back agwin. Thereisa steady wind blowing towards he north so that for the fisu slage of the trip, the airplane is nyingin the ans the wind and for the setum trip of the oumer, the airplane is thing dretty ito the wind. The total trip ime T. as compared lothe time in the absenos of army wind

Solution

say the distance between town is S

and the plane speed is V

when there is no wind time of trip T= 2S/V

suppose the velocity of wind is U = tV (t times V)

then total trip time is Tw = S/(V+u)+S/(V-u)

Tw = S/(V+tV)+S/(V-tV) = 2S/V x [1/(1-t²)]

Tw=T x [1/(1-t²)]

it is assumed that wind velocity is less than plane velocity otherwise plane wont be able to reach from town A to town B

term 1-t² < 1 and 1/(1-t²⁾ is more than 1

Tw > T

i think it is option B
