Velocity of a swimmer with respect to a river is (hat i+4hat j)m/s and velocity of the river flow is (2hat j)m/s then velocity of swimmer with respect to ground is (in m/s)

A swimmer's speed in the direction of flow of rivers is 16 km h^-1 . The swimmer's speed in still water and the velocity of flow of the river respectively are.

Two swimmers A and B start swimming from different positions on the same bank as shown in figure.The swimmer A swims at angle 90^(@) with respect to the river to reach point P .He takes 120 seconds to cross the river of width 10m .The swimmer B also takes the same time to reach the point P

Two swimmers P and Q start swimming from different positions on the same bank as shown in the figure. The swimmer P swims at an angle 90^(@) with respect to the river to reach point A. He takes 120 second to cross the river of width 10m. The swimmer Q also takes the same time to reach the point A. the velocity component of Q along x-axis with respect to ground is K/24. Find the value of K.

A swimmer's speed in the direction of flow of a river is 12kmh^(-1) . Against the direction of flow of the river the swimmer's speed is 6kmh^(-1) . Calculate the swimmer's speed in still water and the velocity of the river flow.

A swimmer crosses a river of width d flowing at velocity v. While swimming, he keeps himself always at an angle of 120^(@) with the river flow and on reaching the other end. He finds a drift of d/2 in the direction of flow of river. The speed of the swimmer with respect to the river is :
