A boat goes 8 km an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/ho...
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?
A man takes a total time of 5 hours to cover 36 km downstream and 18 km upstream, while the man takes the same time to cover 54 km downstream and 12 km...
The time taken by a boat to travel 'd' kilometers downstream is 8 hours, while the time taken to travel (d - 60) kilometers upstr...
Speed of a boat in still water is 9 km/hr. It goes 12 km downstream and comes back to the starting point in three hours. What is the speed of water in t...
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.
A man takes 2.2 times as long to row a distance upstream as to row the same distance downstream. If he can row 55 km downstream in 2 hours 30 minutes, w...
A boat can cover 90 km upstream and 225 km downstream in 15 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
The speed of a boat in downstream and upstream is 30 km/hr and 22 km/hr, respectively. Find the approximate time taken by the boa...
A boat covers a distance of 150 km while moving in a downstream in 5 hours. When the boat covers a distance of 60 km in still water in 3 hours, then Wha...
