A swimmer swins in still water at a speed =5 km//hr . He enters a 200m wide river, having river flow speed =4km//hr at point A and proceeds to swim at an angle of 127^(@) (sin 37^(@) = 0.6) with the river flow direction. Another point B is located directly across A on the other side. the swimmer lands on the other bank at a point C , form which he walks the distance CB with a speed = 3km//hr . The total time in which he reaces from A to B is

A swimmer wants to cross a 200 m wide river which is flowing at a speed of 2 m/s. the velocity of the swimmer with respect to the river is 1 m/s. how far from the point directly opposite to the starting point does the swimmer reach the opposite bank ?

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 river is of width 120m which flows at a speed pf 8ms^(-1) . If a man swims with a speed of 5ms^(-1) at an angle of 127^(@) with the stream, his drift on reaching other bank is

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 drift of the man along the direction of flow, when he arrives at the opposite bank is.

A swimmer can swim in still water at a rate 4.0 km/h. If he swims in a river flowing at 3.0 km/h and keeps his direction (with respect to water) perpendicular to the current, find his velocity with respect to the ground.
