The speed of a boat in upstream is 100 kmph and the speed of the boat downstream is 112 kmph. Find the speed of the boat in still water and the speed of the stream?	Choose one:
A) 70, 10 kmph  B) 106, 6 kmph  C) 50, 60 kmph  D) 45, 55 kmph  E) 45, 65 kmph
Speed of the boat in still water = (100+112)/2=
