Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 20 minutes to cover 20 km in downstream, then find th...
When travelling downstream, a boat takes 6.25 hours to travel 275 km. If the speed of the stream is (4/11)th of downstream speed of the boat,...
A boat can travel 38 km downstream in 57 min. The ratio of the speed of the boat in still water to the speed of the stream is 3: 2. How much time will t...
The ratio of the speed of a motorboat to that of a current of water is 36:5. The boat goes along with the current in 5 hours and 10 minutes it will come...
Speed of a boat in still water is 6 times more than the speed of stream. If boat covers 144 km in downstream in 9 hours, then find the time taken by the...
A boat takes one-third time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of the cur...
Find the total distance covered by boat in still water in 8 hours if the speed of boat in upstream and in downstream is 10 km/h and 15 km/h respectively?
