Two boats A and B are stationed at two points Q and R on a flowing river. The direction of flow of river is from Q to R. When the boats A and B moved towards each other they met at P, Which is at a distance of 20 m from the point R. When A moves towards B and B moves away from A they met at S which is at a distance of 40 m from the point R. Boat B's speed in still water is 5 times the speed at which river is flowing. Find the ratio of the speed of boat A to boat B 1. 6:1 8:1 3. 5:1 4. 7:1 None of these 2. 5. Two boats A and B are stationed at two points Q and R on a flowing river.
