Question
A man can row 16 km/hr in still water. It takes him
thrice as long to row up as to row down the river. Find the speed of the man against the current.Solution
Let man’s rate upstream be x kmph. Then his rate downstream = 3x kmph. 
Rate in still water =   kmph = 2x kmph 16 = 2x x = = 8, So, Rate upstream = 8 kmph.
