```							The speed of the river is 2 km/hr.Explanation:Given that,Velocity of swimmer = 4 km/hrAngle = 120°We need to draw a figure,Here,  is the velocity of swimmer w.r.to river,  is the velocity of river w.r. to ground and V is the velocity of swimmer w.r.to ground.    Put the value in equation (I)  Hence, The speed of the river is 2 km/hr.
