A man can row 14 Kmph in still water. It takes him twice as long to row up as to row down the river. Find the rate of stream?	Pick one:
A) 17.6 Km/hr  B) 18.6 Km/hr  C) 19.6 Km/hr  D) 18.6 m/hr  E) None of these
Explanation:   Let man's rate upstream be x kmph   Then his rate downstream = 2x kmph   Rate in still water = 1/2 (2x + x)   3x/2= 14 Kmph   3x = 28   x = 9.3   Rate of upstream = 9.3 Km/hr   Rate of downstream =18.6 Km/hr   Answer: Option 18.6 Km/hr
