Question : Two trains are moving with equal speed in opposite directions along two parallel railway tracks. If the wind is blowing with speed 𝑢 along the track so that the relative velocities of the trains with respect to the wind are in the ratio 1: 2, then the speed of each train must be

(A) 3𝑢

(B) 2𝑢

(D) 4𝑢

Answer : option (A)

Solution :

Two trains are moving with equal speed in opposite directions along two parallel railway tracks. If the wind is blowing with speed 𝑢 along the track so that the relative velocities of the trains with respect to the wind are in the ratio 1: 2, then the speed of each train must be
