An aeroplane has to go along straight line from A to B, and back again. The relative speed with respect to wind is V. The wind blows perpendicular to line AB with speed υ . The distance between A and B is λ . The total time for the round trip is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For no drift
V sin θ = υ
sin θ = 
∴ t = t AB + t BA
t = 
= 
t =
