Problems on Boat and 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.

A boatman takes twice as long to row a distance against the stream as to row the same distance with the stream.Find the ratio of speeds of the boat in still water and the stream.

A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is :
