A man rows to a place 48 Km distance and back in 14 hours. He finds that he can row 4 Km with the stream in the same time 3 Km against the stream. The rate off the stream is?  Pick.
A) 5	B) 3	C) 2	D) 1	E) 4
Let be moves 4km downstream in X Hours   Then in speed downstream = Kmph   Speed in upstream = 4/X Kmph   ==&gt; 48/4/X + 48/3/X = 14   ==&gt; 12X + 16X =14   ==&gt; X = 1/2   Speed in downstream = 8 Kmph   Speed in up stream = 6 Kmph   Then the Rate of stream = 1/2 (8 - 6) = 1 Kmph   Answer is 1.
