Question

The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in still water. If boat ‘A’ takes 7 hours to travel 700 km downstream, then find the time taken by boat ‘B’ to travel 140 km upstream and 220 km downstream. (Note: Both the boats are rowing in the same stream.)

A 2 hours

B 4 hours

C 3 hours

D 6 hours

E None of these
