```							Vb=velocity of the boat and side AB represents Vb Vc=velocity of water current and side BC represents Vc  Vb=7.2 kmph = 2 m/sec  Time taken by the boat to cross the river 500 /2 = 250sec = 4.16min  Drift experienced by the boat BC=Vc*t = 150Vc = 150/250 =  0.6 m / sec Regards,Arun(AskIITians Forum Expert)
