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:
When travelling downstream, a boat takes 6 hours to travel 240 km. If the speed of the stream is (3/8)th of downstream speed of the boat, the...
A boat covers 36 km downstream in 2 hours, and it takes 3 hours to cover the same distance upstream. What is the speed of the current?
A man can row 25/2 km an hour in still water and he finds that it takes him thrice as long to row up as to row down the river. The rate of stream is:
A man can row 16 km/hr in still water. If the speed of the current is 4 km/hr, it takes 5 hours more in upstream than in the downstream for the same dis...
The ratio of the speed of boat in upstream to speed of boat in downstream is 7:9. If the boat can cover a total of 70 km upstream and 144 km downstream ...
Two boats X and Y start towards each other from two places, 155 km apart. Speed of the boat X and Y in still water are 14 km/hr and 17 km/hr respectivel...
The ratio of the speed of the boat in upstream to that of in downstream is 5:9, respectively. If the speed of the current is 7 km/h, then find the speed...
The ratio of the speed of the boat in upstream to that of in downstream is 3:4, respectively. If the speed of the current is 5 km/h, then find the speed...
