The velocity of a vessel in calm waters is 4.5 times the speed of the current. If the disparity between the boat's speed when moving against the current...
A boat travels faster than the stream by 28 km/h. It covers a distance of 112 km upstream and returns 132 km downstream, all within 7 hours. Calculate t...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 25 minutes to cover 25 km in downstream, then find th...
The speed of a boat going upstream is 20% slower than when it is traveling downstream. The boat travels 90 km in still water over a period of 4 hours. C...
The speed of boat downstream and upstream is 30 km/hr and 20 km/hr respectively. Time taken to travel a distance of (a + 50) km downstream and (b + 25) ...
The circumference of the two circles is 110 cm and 330 cm respectively. What is the difference between their radii?
The speed of a boat in still water is 5 km/hr and speed of current is 3 km/hr. If time taken to cover a certain distance upstream is 12 hours, then how ...
The speed of a boat in still water is 11 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 20 k...
The ratio of the speed of a boat in still water to its speed in downstream is 6:8. If the difference between the time taken by the boat to travel 288 km...
A ship covers a distance of 240 km downstream in a time that is 2 hours shorter than the time it takes to cover the same distance upstream. The ship's u...
