A swimmer can swim at 3 sqrt(2) km*h^(-1) in still water. He swims across a river when the velocity of current is 3 km *h^(-1). (ii) Inwhat direction should he swimto cross the river in minimum time ? In that case how far will he be carried by the river current if the river is sqrt(2) km wide ?

1.	A swimmer can swim at 3 sqrt(2) kmh^(-1) in still water. He swims across a river when the velocity of current is 3 km h^(-1). (ii) Inwhat direction should he swimto cross the river in minimum time ? In that case how far will he be carried by the river current if the river is sqrt(2) km wide ?
Answer» ANSWER :`90^@` to the direction ofcurrent of CURRENT ,1 km
