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 54 km downstream?
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
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 ...
Speed of a boat in still water is 9 kmph and speed of stream is 6 kmph. A man rows to a place at a distance of 30 km and come back to starting point. Th...
Speed of a boat in still water to speed of boat in upstream is 8: 7. If the boat can travel 450 km in downstream in 10 hours, then find the time taken b...
