A boat takes 34 hours to travel from P to Q upstream and from Q to P downstream. If the speed of the boat in still water is 8.5 km/h and the speed of th...
A boat covers a distance of 90 km downstream in 3 hours. If the ratio of upstream speed to downstream speed of the boat is 3:9, then find the distance t...
A man can row at 2 kmph in still water. If the velocity of current is 1 kmph and it takes him 4 hour to row to a place and come back, how far is the place?
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 rows a certain distance downstream in 5 hours and back to the same point in 8 hours. If the speed of the stream is 4.5 km/hr then what is the spee...
Speed of a boat in still water to speed of boat in upstream is 11: 9. If the boat can travel 260 km in downstream in 10 hours, then find the time taken ...
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 boat can travel 42 km downstream in 60 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 2. How much time will t...
The ratio of the distances traveled by a boat in upstream and downstream is 6:7, respectively, and the total time taken to cover the desired distance is...
The downstream speed of a boat is 6 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
