Two ports, A and B, on a north-south line ar separated by a river of width D. The river flows east with speed u. A boat crosses the river starting from port A. The speed of the boat relative to the river is v. Assume `v=2u`
Q. What is the direction of the velocity of boat relative to river `theta`, sothat it crosses directly on a line from A to B?

Two ports, A and B, on a north-south line ar separated by a river of width D. The river flows east with speed u. A boat crosses the river starting from port A. The speed of the boat relative to the river is v. Assume v=2u Q. The boat crosses the river from A to the other side in shortest possible time, then how far is the boat from the port B after crossing the river

Two ports, A and B, on a north-south line ar separated by a river of width D. The river flows east with speed u. A boat crosses the river starting from port A. The speed of the boat relative to the river is v. Assume v=2u Q. Suppose the boat wants to cross the river from A to the other side in the shortest possible time. Then what should be the direction of the velocity of boat relative to river?

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 man who can swim at a speed v relative to the water wants to cross a river of width d flowing with a speed u. The point opposite him across the river is A.

A man who can swim at a velocity v relative to water wants to cross a river of width b, flowing with a speed u.
