In the previous problem, How far from the point directly opposite to the starting point does the man reach the opposite bank

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:

A river is 20 m wide. River speed is 3 m//s. A boat starts with velocity 2sqrt2 m//s at angle 45^@ from the river current (relative to river) (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank?

A 400 - m wide river is flowing at a rate of 2.0 m s^-1 . A boat is sailing with a velocity of 10 m s^-1 with respect to the water, in a direction perpendicular to the river. (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank ? ( c) In what direction does the boat actually move ?

A river 400 m wide is flowing at a rate of 2.0 m//s. A boat is sailing at a velocity of 10.0 m//s with respect to the water In a direction perpendicular to the river. (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank?

A river flows with a speed more than the maximum speed with which a person can swim in still water. He intends to cross the river by the shortest possible path (i.e., he wants to reach the point on the opposite bank which directly opposite to the starting point). Which of the following is correct ?

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
