- In a stream running at 2 km/hr, a motor boat goes 10 km upstream and back again to the starting point in 55 minutes. Find the speed of the motor boat in the still water.
- 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?
- 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:
- A man rowing in favour of current can go 80 km in 10 hrs and he can go the same distance in 40 hrs against the current. What is the speed of the current per hour?
- 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?
