The speed of a boat in still water is twice the speed of the current. If the boat takes 10 hours to cover 150 km upstream, then find the time taken by t...
A boat goes 60 km upstream in 4 hours and 50 km downstream in 2 hours, then the speed of the boat in still water is
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 48 minutes to cover 24 km in downstream, then find th...
The ratio of the speed of the boat in upstream to that of in downstream is 4:7, respectively. If the speed of the current is 9 km/h, then find the speed...
When travelling with the current, a man takes 4 hours to cover the distance that he would've covered in 12 hours while travelling against the current. ...
The speed of current is 25 km/hr. If the speed of the boat in still water had been 5 km/hr more than the original speed, then it would take 4 hours to c...
In still water, a boat can cover 30 km in 90 minutes. Speed of the stream is 20% of the speed of the boat in downstream. Find the time taken by the boat...
The speed of the stream is 12 km/h. Boat ‘A’ covers 100 km distance against the stream in 5 hours and boat ‘B’ covers 80 km distance against the...
A boat can cover 80 km upstream and 200 km downstream in 14 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
