What is the speed of man in still water?

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

Statement II: In 20 minutes, the man can swim twice as far with the stream as he can against the stream.

If the data in statement I alone is sufficient to answer the question.

If the data in statement II alone is sufficient to answer the question.

Explanation:

From Statement I, speed of stream = x km/hr then man’s speed = 3x 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, 2d/(a+b) = d/(b-a)
We get the same statement as I, man’s speed (b) = 3 times speed of stream (a).
Thus both the statements are not sufficient to answer the question.

Hence, option 4 is the correct answer.
