What is the speed of man in still water?

Statement I : The speed of man in still water is twice the speed of the stream.

Statement II : In 30 minutes, the man can swim thrice as far with the stream as he can against the stream.

From Statement I, Speed of stream = x km/hr then man’s speed = 2x km/hr From Statement II, Let speed of stream = a km/hr and man’s speed = b km/hr since times is equal to travel upstream and downstream, 3d/(a+b) = d/(b- a ) we get the same statement as I, Man’s speed (b) = 2 times speed of stream (a). Thus both the statements are not sufficient to answer the question.
