A man can row upstream 10 kmph and downstream 20 kmph. Find the man rate in sƟll water and rate
of the stream.	Select
A) 0,5
B) 5,5
C) 15,5
D) 10,5
E) None of these
Explanation:   Please remember,   If a is rate downstream and b is rate upstream   Rate in still water = 1/2(a+b)   Rate of current = 1/2(a-b)   =&gt; Rate in still water = 1/2(20+10) = 15 kmph   =&gt; Rate of current = 1/2(20-10) = 5 kmph   Answer: 15,5
