Because of inadequate data none of the assumptions is implicit.
The speed of boat downstream and upstream is 36 km/hr and 26 km/hr respectively. Time taken to travel a distance of (k + 60) km downstream and (l + 40) ...
The boat's speed in still water is 20% greater than the speed of the stream. If it takes the boat 4 hours more to travel 176 km d...
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...
The speed of the boat A and B in still water are in the ratio 15:13. The speed of the current for both boats is 16 km/hr. If the sum of time taken by bo...
The ratio of speed of boat in upstream and in Stillwater is 1: 3 respectively. The boat takes a total of 10 hours to travel 300 kilometer in downstream ...
A man can row at 4 kmph in still water. If the velocity of current is 3 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
The speed of boat in still water is 48 kmph. If it takes 5 hour to go upstream 40 kms, in what time approximately will it return same distance downstrea...
A boat covers 35 km downstream in 2 h and covers the same distance upstream in 7 h. Find the speed (in km/h) of the boat in still water.
A boat travels 36 km upstream and 48 km downstream in 8 hours. If the speed of the stream is 3 km/h and the boat’s speed in still water is 9 km/h, wha...
