[Audio] Today let's talk about river boat problem. River boat problem is the basic problem that is faced by the people who live near the bank of the river. In this video we will discuss about the shortest distance that we need to cross the river. Let us suppose d be the distance between the banks of the river. Shortest distance is the straight line between the banks of river.

[Audio] Let's sail a boat from one bank to another to cover a shortest distance. Wait! What just happened?.

[Audio] Here, the velocity of boat is Vb and velocity of river is Vr where both are acting perpendicularly..

[Audio] While sailing the boat, the velocity of river cannot change the horizontal velocity of boat but it can change the vertical velocity of boat. So that, the path followed by boat is shifted by an angle. The path followed by a boat is its resultant velocity V..

[Audio] Then how can we cover the shortest distance? Hmmm…...

[Audio] The resultant velocity is V2 = Vb2 – Vr2.
