A boat travels in a river where the current flows at a speed of 5 km/h. The total time taken by the boat to go from point 'P' to ...
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 cover a distance of 64 km downstream in 4 hours less time than it takes to travel the same distance upstream. If the current of the stream fl...
The speed of a boat in still water is three times the speed of the boat upstream. If the boat takes 30 minutes to cover 27 km downstream, then find the ...
A boatman takes 9 hours to cover 64 km downstream and 60 km upstream. If the ratio of his speed downstream to his speed upstream is 4:3, what is the spe...
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
A man rows upstream 18 km and downstream 30 km taking 6 hours each. Find the man’s speed in still water.
The speed of current is 29 km/hr. If the speed of the boat in still water had been 17 km/hr more than the original speed then it would take 6.2 hours to...
The speed of boat downstream and upstream is 28 km/hr and 18 km/hr respectively. Time taken to travel a distance of (m + 35) km downstream and (n + 22) ...
The downstream speed of a boat is 75% greater than its upstream speed, and the speed of the stream is 3 m/s. How far can the boat travel in still water ...
