The ratio of the speed of the boat in upstream to that of in downstream is 7:10, respectively. If the speed of the current is 12 km/h, then find the spe...
The ratio of the speed of the boat in upstream to that of in downstream is 2:3, respectively. If the speed of the current is 6 km/h, then find the speed...
A boat goes 56 km in upstream in 4 hours and takes 3 hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.
A boat takes 270 minutes to travel 90 km in upstream. The same boat in the same stream takes 120 minutes to travel 50 km in downstream. Find the distanc...
The speed of a boat in downstream is 20% more than speed of boat in still water. If the boat travels a distance of 90 km upstream in 15 hours then find...
Speed of current is equal to 35% of speed of boat in still water. If the boat takes 7 hours to cover 140 km in still water, then find the time taken by ...
Determine the speed of a Ship in calm water, given that the Ship's speed downstream is 20% greater than its speed in still water. If the Ship can cover ...
A boat can cover 72 km upstream and 180 km downstream in 12 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
The downstream speed of a boat is 4 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 man can row at 7 kmph in still water. If the velocity of current is 5 kmph and it takes him 7 hour to row to a place and come back, how far is the place?
