Boats and Streams Questions

Ramu can row 9 kmph in still water. It takes him twice as long to row up as to row down. Find the rate of stream.

If the speed of a boat in still water is 20 km/hr and the speed of the current is 5 km/hr, then the time taken by the boat to travel 100 km with the current is

Speed of a boat along and against the current are 14 kms/hr and 8 kms/hr respectively. The speed of the current is
