A swimmer wants to cross a river which is flowing at a speed ' v '. If the swimmer can swim in still water at speed ' V ', the direction he should swim to cross the river in least time is

Options

  1. AAlong the flow of river
  2. BOpposite to the flow of river
  3. CPerpendicular to the flow of river
  4. D45^ to the flow of river

Correct answer

C. Perpendicular to the flow of river

Step-by-step solution

If the swimmer wants to cross the river in least time than he must swim perpendicular to the flow of the river.
