5. Two boats, X and Y started travelling towards each other from point M and point N respectively at the same time, where point M and N are the end points of the river. On reaching another end point, both boats return to the same end point from where they had started. The speed of boat X in still water is 10 km/h less than the speed of boat Y in still water. Both boats meet for the first time after (84/11) hours of their start. If the speed of stream is 2.5 km/h which is flowing from point M to point N and the length of the river is 420 km, then after how much time of start will both boats meet for the second time? A. 22.65 hours B. 22.75 hours C. 20.84 hours D. 24.72 hours E. None of these
