A man can row downstream at the rate of 45 Kmph and upstream at 23 Kmph. Find the man’s rate in still water and rate of current? Choose the correct choice from the following answers:
A) 8.5 B) 10.0 C) 12.5 D) 11.0 E) 8.25
Rate of still water = 1/2 (down stream + upstream)   = 1/2 (45 + 23) = 34 Kmph   rate of current = 1/2 (down stream - upstream)   = 1/2 (45 - 23)   = 1/2 (22)   = 11 kmph   Answer is 11.0.
