Dear Readers, As you know that All the basic C oncepts of Time speed and Distance apply to this chapter Boats and streams.

Still Water : If the water is not moving then it is called still water. Upstream : If a boat or a swimmer moves in the opposite direction of the stream then it is called upstream.
