- Speed of the boat in standing water is 6 km/h and the speed of the stream is 2 km/h. What will be the total time if a man goes by the boat upstream 32 km and comes back to the starting point?
- The velocity of a boat rowed downstream is three times that of the same boat rowed upstream. If the speed of the stream is 2.5 miles per hour what is the speed of rowing in miles/hr?
- A man can now a boat at 10 km/hr in still water. If the speed of the stream is 6 km/hr, the time teken to row a distance of 80 km downstream is:
- If a man row at 10 km/h along the current & the rate of the current is 2 km/h, what is the man's rate against the current?
- A man can rows 6 km/hr in still water. When the river is running at 1.5 km/hr, it takes him 1.5 hour to row to a place and back. How far is the place?
