A boat can travel 26 km downstream in 30 min. The ratio of the speed of the boat in still water to the speed of the stream is 8: 5. How much time will t...
- A boat takes the same amount of time to travel (x – 24) km upstream as it takes to cover (2x – 84) km downstream. If the speed of the boat is 12 km/h a...
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 11:5:2, respectively. If...
If the sum of upstream and downstream speed is 24 km/hr and the speed of the current is 5 km/hr, then find the approximate time taken to cover 36 km dow...
The speed of a motorboat in still water is 25 km/h and the speed of the stream is 5 km/h. The boat first goes 120 km downstream and then covers a certa...
A boat takes 24 hours to cover 'q' km in still water. While traveling downstream, it takes 16 hours to cover (q - 80) km. If the speed of the boat in st...
A man rows upstream 10 km and downstream 15 km taking 5 hours each. Find the speed of current.
...A swimmer swims from a point A against a current for 12 minutes and then swims backwards in favour of the current for next 12 minutes and comes to the p...
A ship, when moving against the current, can travel a distance of 240 km in 8 hours. If the ship's speed in calm waters is 40 km/hr, how many hours will...
The speed of a boat in still water is 30 km/hr. If the boat covers 160 km in upstream in 8 hours, then find the time taken by the boat to travel 120 km ...
