The correct answer is C
The ratio of the speed of the boat in upstream to that of in downstream is 5:9, respectively. If the speed of the current is 7 km/h, then find the speed...
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.
A boat covers a distance of 108 km downstream in 3 hours. If the ratio of upstream speed to downstream speed of the boat is 5:9, then find the distance ...
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 54 km downstream?
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 ...
A boat can row to a place of 60km away and come back in
The speed of the boat in still water is 10 km/hr and the speed of the stream is 5 km/hr. A boat goes 75 km downstream with its usual speed but at the ti...
The speed of a boat in still water is 15 km/hr. If the boat covers 120 km in upstream in 12 hours, then find the time taken by the boat to travel 120 km...
A boat goes 5 km an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/ho...
A boat can travel 21 km downstream in 42 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 1. How much time will t...
