Question
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 7:5:2, respectively. If the time taken by boat ‘A’ to travel (6D – 30) km downstream is equal to the time taken by boat ‘B’ to travel (D + 60) km upstream, then find the value of ‘D’.
