Question
The speed of boat 'A' in upstream and still water is in the ratio of 3:5. The boat takes 16 hours to travel 175 km downstream and 275 km in still water. The still water speed of boat 'B' is 20% less than that of boat 'A'. If the speed of the stream increases by 20%, determine the time required for boat 'B' to cover 480 km downstream and 360 km upstream.
