Find the total distance covered by boat in each upstream and downstream in 6 hours if the speed of boat in still water and speed of current is 15 km/h a...
A man can row 8 km/hr in still water. If the speed of the current is 2 km/hr, it takes 5 hours more in upstream than in the downstream for the same dist...
The speed of a boat in still water is three times the speed of the boat upstream. If the boat takes 30 minutes to cover 27 km downstream, then find the ...
A boat takes a total of 1.5 hours to cover 20km upstream and 15 km downstream. If the boat takes 4.8 hours to cover 120 km in still water, then find the...
A boat takes half the time to move a certain distance downstream than upstream. the ratio of the boat's speed in still water and that of the current is.
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream?
Before rain a boat can cover 90 km in still water and the same distance upstream in 6 hours and 9 hours, respectively. Due to the rain the speed of the ...
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 boat goes 200 km downstream in 50 hours, and 90 km upstream in 30 hours. The speed of the stream is
Speed of a boat in still water to speed of boat in upstream is 13:10. If the boat can travel 320 km in downstream in 5 hours, then find the time taken b...
