Velocity of boat -8-82-8-xA0-km-h

A boat takes $2$ hours to travel $8 k m$ and back in still water lake. With water velocity of $4 k m / h$ , the time taken for going upstream of $8 k m$ and coming back is
$160 m i n u t e s$
$80 m i n u t e s$
$100 m i n u t e s$
$120 m i n u t e s$

Velocity of boat $= \frac{8 + 8}{2} = 8 k m / h$
