Boat A is running from point P to point Q against the river and B is moving from point Q to point P in the direction of flow of the river. The speed of boat A in still water is 28 km/hr and the ratio of the speed of boat A while travelling upstream to speed of boat B while travelling downstream in the river is 3:4 respectively. Boat A and Boat B start from their respective sources simultaneously but after 4 hours 24 minutes due to technical problem speed of boat B reduces by 25%. If both cases cross each other in 6 hours from the start then, find the distance between P and Q.
ans 324.8km
