- 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:
- 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?
- 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 certain river has a current of 3 miles per hour. A boat takes twice as long to travel upstream between two points as it does to travel downstream between the same two points. What is the speed of the boat in still water?
- 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?
