Most Important Formulas of Boat And Stream

BOAT AND STREAM

The direction along the stream is known as downstream. Direction against the stream is known as upstream. The moving of water in a river or sea is known as a stream.

CONCEPT

If speed of boat in still water is 'U' km/h & speed of stream is V km/h Then,

• Speed Downstream = (U + V) km/hr
• speed Upstream = (U – V) km/h

If the speed downstream is 'a' km/h & the speed upstream is 'b' km/h Then,

• Speed in still water = ½ (a+ b) km/h
•    Speed of stream =   ½ (a–b) km/h

Some more tips and tricks

Let's assume that a boy can row at a speed of A km/h in still water & he rows the same distance up & down in a stream that flows at a rate of B km/h. Then his average speed throughout the journey-
=   km/h

• Let’s the speed of a boy in still water be A km/h and the speed of the stream be B km/hr. If he takes ‘X’ hours more upstream than to go downstream for the same distance. Then the distance= km
• A boy can row a certain distance in still water at A km/hr. In a stream flowing at B km/hr, if it takes him t hours to row a place and come back, then the distance between two points =
• A boy rows a certain distance downstream in t1 hours and returns the same distance upstream in t2 hours. If the speed of the stream is A km/hr, Then the speed of the boy in still water=
