A man swims downstream 60 km and upstream 36 km, taking 12 hr each time. Find the man’s rate in still water?
A boy can swim in water with a speed of 12 km/hr in still water. If the speed of the stream is 6 km/hr, what will be the time taken by the boy to cover ...
When travelling downstream, a boat takes 4.25 hours to travel 187 km. If the speed of the stream is (5/11)th of downstream speed of the boat,...
If Boat goes 80 km upstream in 4 hours and 60 km downstream in 2 hours, then the speed of the boat in still water is
A boat can travel 28 km downstream in 30 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 3. How much time will t...
A boat can cover 66 km upstream and 165 km downstream in 13 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
A boat takes half the time to move a certain distance downstream than upstream. the ratio of the boat's speed in still water and that of the current is.
What is the difference between the mode and the meaning of the observations?
