What is the speed of the boat in still water?
I.The boat covers a distance of 48 km downstream in four hours.
II.The boat while traveling upstream took thrice the time it took to cover the same distance as that on downstream.
III.The speed of the current is 6kmph.

Correct

Explanation:
X=speed of boat,y=speed of current
From I- 48/(x+y)=4
From II-d/(x-y)=3d/(x+y)
Therefore x=2y
From III-y=6
Hence any two are sufficient

Incorrect

Explanation:
X=speed of boat,y=speed of current
From I- 48/(x+y)=4
From II-d/(x-y)=3d/(x+y)
Therefore x=2y
From III-y=6
Hence any two are sufficient
