A man can swim at 4 m/s in a still water swimming pool. He enters a 200 m wide river at one bank and swims ( w.r.t water) at an angle of `60^(@)` to the river flow velocity. The river flow velocity is 5 m/s . In how much -time does he cross the river ? Calculate his drift.

A man can swim at a speed of 3 km h^-1 in still water. He wants to cross a 500-m wide river flowing at 2 km h^-1 . He keeps himself always at an angle to 120^@ with the river flow while swimming. The time taken to cross the river is.

A boat can be rowed at 5 m/s on still water. It is used to cross a 200m wide river from the south bank to the north bank. The river current has uniform velocity of 3 m/s due east. (a) In which direction must it be steered to cross the river perpendicular to current ? (b) How long will it take to cross the river in a direction perpendicular to the river flow ? (c) In which direction must the boat be steered to cross the river in minimum time ? How far will it drift ?
