- 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 rows upstream 24 km and downstream 36 km, taking 6 hours each time. The velocity of the current will be:
- A man can row upstream at 10 km/h and downstream at 16 km/h. His rate in still water is---
- 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 can row downstream at 14 km/h and upstream at 8 km/hr. What is the rate of the stream?
