Solve the previous problem , if particles moving in opposite direction.

A boatman moves his boat with a velocity 'v' (relative to water) in river and finds to his surprise that velocity of river 'u' (with respect to ground) is more than 'v'. He has to reach a point directly opposite to the starting point on another bank by travelling minimum possible distance. Then

A man can swim at the rate of 5 kmh^(-1) in still water A. One km wide river flows at the rate of 3 kmh^(-1) . The man wishes to swim across the river directly opposite to the starting point. How much time will be take to cross the river

A man can swim with a certain speed, in still water to cross a river to a point directly opposite to the starting point in time t_(0) . When the river flows, he crosses the river directly along the same path in a time t_(1) , If 'd' be the river width, Then the velocity of water current is:
