A boat can cover 160 km in downstream in 16 hours and 144 km in upstream in 18 hours. Find the speed of boat in still water
The speed of current is 10 km/hr. If the speed of the boat in still water had been 8 km/hr more than the original speed, then it would take 7 hours to c...
A ship requires 9 hours to travel a distance of 216 km downstream and 210 km upstream. If the ratio of the ship's speed in calm waters to the speed of t...
A boat goes x km downstream from A to B and then returns upstream to D, where BD = x/1.8. If total time taken is 52 hours, boat speed in still water is ...
Boat speed in still water = 12 km/h, stream speed = 3 km/h. Time to go 30 km downstream and return 30 km upstream?
- Ratio of speed of a boat in still water to speed of stream is 9:1 respectively.Ratio of the time taken by the boat to cover a distance of (x + 50) km upstr...
Ratio of speed of boat in downstream and speed of stream is 7:4, if speed of current is 8 km/hr, then find distance travelled (in km) upstream in 7 hours.
Speed of a boat in still water to speed of boat in upstream is 11: 9. If the boat can travel 260 km in downstream in 10 hours, then find the time taken ...
The speed of a boat in still water is 6 km/hr more than that of the current. The time taken by the boat to cover 675 km downstream is 13.5 hours. Find t...
The speed of the stream is 14 km/h. Boat ‘A’ covers 130 km distance against the stream in 5 hours and boat ‘B’ covers 100 km distance against th...
