A boat goes 56 km in upstream in 4 hours and takes 3 hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.
A boat, whose speed in still water is 25% more than the speed of the current, covers 810 km downstream in _____ hours. The speed of the boat in still wa...
A boat can travel 28 km downstream in 30 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 3. How much time will t...
The speed of a boat in still water is 26 km/hr. If the boat covers 75 km in upstream in 5 hours, then find the time taken by the boat to travel 111 km i...
A man can row at 4 kmph in still water. If the velocity of current is 2 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
Speed of a boat in downstream is 50% more than that in upstream. Total time to travel 48 km upstream and 36 km downstream is 6 hours. What is the speed ...
Find the total distance covered by boat in each upstream and downstream in 4 hours if the speed of boat in still water and speed of current is 15 km/h a...
A boat can cover 12 kilometers in still water in 40 minutes. If the speed of the current is 2 kilometers per hour, then what is the average speed it tak...
The speed of the stream is 10 km/h. Boat ‘A’ covers 180 km distance against the stream in 6 hours and boat ‘B’ covers 90 km distance against the...
