A boat travels a certain distance downstream in 72 minutes but takes 3 hours to cover the same distance upstream. The speed of the stream is 15 km/h. If...
A boat takes 1/4th time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of current is?
A man takes 2.2 times as long to row a distance upstream as to row the same distance downstream. If he can row 55 km downstream in 2 hours 30 minutes, w...
Speed of a boat in still water is 4 times more than the speed of stream. If boat covers 126 km in downstream in 7 hours, then find the time taken by the...
A boat can travel 30 km downstream in 45 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 man can go on a motor boat with a speed of 15 km/hour in still water to a certain upstream point and come back to the starting point in a river which ...
The speed of current is 26 km/hr. If the speed of the boat in still water had been 12 km/hr more than the original speed then it would take 7.5 hours to...
The Speed of the ship in calm water is five times the speed of the stream. If the ship can travel 's + 30' km downstream or 's - 10' km upstream in 5 ho...
A man rows to a place 42 km away and comes back to the starting point. If the speed of the stream is 2 km/hr and the speed of the boat in still water is...
A man can row at a speed of 20 km/hr in still water to a certain upstream point and back to the starting point in a river which flows at 5 km/hr. Find h...
