- A man can row downstream at 10 kmph and upstream at 5 kmp. The man's rowing rate in still water is--
- 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 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?
- A man rows upstream 24 km and downstream 36 km, taking 6 hours each time. The velocity of the current will be:
- 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?
