47.A man can row a boat with 4kmph in still water.If he is crossing a river where the current is 8kmph .The time take to cross the river in shortest path is (k)/(sqrt(3))hr .Where k ' is (width of the river is 8km )

A river is flowing towards with a velocity of 5 m s^-1 . The boat velocity is 10 ms^-1 . The boat crosses the river by shortest path. Hence,

A swimmer crosses the river along the line making an angle of 45^@ with the direction of flow. Velocity of the river water is 5(m)/(s) . Swimmer takes 12 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be:

A boat crosses a river of width 1 km by shortest path in 15 min. if the speed of boat in still water is 5 kmh^(-1) , then what is the speed of the river?

A swimmer crosses the river along the line making an angle of 45^(@) with the direction of flow. Velocity of the river is 5 m/s. Swimmer takes 6 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be :

A man in a boat crosses a river from point A. If he rows perpendicular to the banks he reaches point C (BC = 120 m) in 10 min. If the man heads at a certain angle alpha to the straight line AB (AB is perpendicular to the banks) against the current he reaches point B in 12.5 min. Find the width of the river w, the rowing velocity u, the speed of the river current v and the angle alpha . Assume the velocity of the boat relative to water to be constant and the same magnitude in both cases.
