Solution

The correct option is A $8 h$
Distance $= 128$ km
Speed of water $= 24$ km/h
Speed of stream $= 8$ km/h
Net speed of boat
$= (24 - 8)$ km/h
$= 16$ km/h
Speed $= \frac{D i s t a n c e}{T i m e}$
$\Rightarrow$ Time $= \frac{D i s t a n c e}{S p e e d}$
$= \frac{128 k m}{16 k m / h}$
Time $= 8$ h.
