A boat travels 36 km upstream and 48 km downstream in 8 hours. If the speed of the stream is 3 km/h and the boat’s speed in still water is 9 km/h, wha...
A boat can travel 26 km downstream in 30 min. The ratio of the speed of the boat in still water to the speed of the stream is 8: 5. How much time will t...
A boat goes 40 km in upstream in 5 hours and takes 3 hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.
A man can row at 36 km/hr in still water. In a stream which is flowing at 12 km/hr, it takes him 3 hrs to a place and back. How far is the place?
The combined speeds of boats 'P' and 'Q' in still water amount to 52 km/hr. The current's speed affecting boat 'P' is 25% greater than that affecting bo...
If the speed of a boat in a still water is 20 km per hour and the speed of current is 5 km per hour then the time taken by the boat to travel 100 KM wit...
Boat ‘A’ can cover 180 km in still water in 12 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 3:4 and the sp...
Speed of a boat in still water is 11 kmph and speed of stream is 9 kmph. A man rows to a place at a distance of 40 km and come back to starting point. T...
The speed of boat downstream and upstream is 26 km/hr and 22 km/hr respectively. Time taken to travel a distance of (p + 45) km downstream and (q + 30) ...
A boat travels downstream at a speed that is (13/12) times its speed in still water. If the boat takes 3 hours to cover 132 km going upstream, how long ...
