A boat can cover ‘y’ km distance downstream in (t+2.5) hours. The same boat can cover ‘0.25y’ km distance upstream in ‘t’ hours. The time ta...
The ratio of the speed of boat in upstream to speed of boat in downstream is 7:9. If the boat can cover a total of 70 km upstream and 144 km downstream ...
The speed of current is 18 km/hr. If the speed of the boat in still water had been 7 km/hr more than the original speed, then it would take 8 hours to c...
A man swims 3km/h against the stream and goes 1 km in 10 minutes along the stream, how much time will it take to cover 5 km in still water?
A boat travels 40 km downstream in 5 hours, and the same boat travels 40 km upstream in 8 hours. Find the speed of the boat in still water.
A boat covers 32 km upstream and 40km downstream in 8 hours while it covers 40km upstream and 32 km downstream in 8.5 hours. What is the velocity of cur...
The total time taken by a boat to cover a certain distance in downstream and the same distance in upstream is 10 hours. The same boat can cove...
The time taken by a boat to travel (5p + 60) km upstream is equal to the time taken to travel (8p - 40) km downstream. Given that...
A boat takes 7 hours to cover 245 km upstream and 9 hours to cover 477 km downstream. Find the time taken by the boat to cover 410 km upstream and 495 k...
The stream flows at 2 km/h. A boat takes 1 hour more to cover 36 km upstream than it takes to go 40 km downstream. What is the distance the boat can cov...
