A ferry takes 108 minutes to row to place B from another place A along the stream. The distance between place A and place B is 32.4 km. If the speed of the ferry in still water is seven times more than that of the stream, then how much distance will the ferry cover in 6.4 hours against the stream?
Let the speed of the stream be 'M' km/h Speed of the ferry in still water = (7M + M) = 8M km/h Downstream speed = (8M + M) = 9M km/h Upstream speed = (8M – M) = 7M km/h Acc. to the question, 32.4 = 9M × (108/60) M = 2 km/h Upstream speed = 7M = 7 × 2 = 14 km/h Distance travelled = 6.4 × 14 = 89.6 km
