Let, the speeds of boat A and boat B, in still water and the speed of the current be 7x kmhr, 5x kmhr and 2x kmhr, respectively. According to the question, 6D 307x 2x D 605x 2x Or, 18D 90 9D 540 Or, 9D 630 Or, D 70

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’.

A 60

B 80

C 70
