Problems on Boat and Stream

Downstream speed of boat is 50 km/h and upstream speed of boat is 30 km/h. Find the speed of boat in still water and speed of stream?

Two boat A and B 20 km apart as shown. Boat a streaming east and boat B in north by 30 km//hr then find shortest approach and time taken for it.

When the speed of a boat in still water is 4 km/h and the rate of stream is 2 km/h, find upstream speed of the boat

Two boats A and b move away form a buoy anchored at the middle of a river along mutually perpendicular staight line. The boat A moves along the stream and the boat B across the river. After moving off an equal distance of 500 metre form the buoy both the voats returned to their original position. Find the ratio of the time taken by boat A to that taken by boat B if the velocity of ecah boat with respect to water is 20m//s and the stream velocity si 10m//s .

What is downstream speed when speed of boat in still water and speed of stream are given

A boat covers a certain distance downstream in 5 hours but takes 7 hours to return upstream to the starting point. If the speed of the stream is 3 km/h, then find the speed of the boat.
