A boat travels from point P to Q and then come back to point P. If speed of boat in still water is doubled, it will take total time of T1 hours in both upstream and downstream together and if boat travels with its original speed, it will take total time of T2 hours in the whole process. If T2 is 110% more than that of T1, find original speed of boat in still water is how much % more than the speed of stream?
