Distance covered by a boat in 5 hours = 36 km
Rate upstream of boat $=\frac{36}{5}$ 7.2 kmph
Speed of the stream = 2.4 kmph
$\therefore$ Speed of the boat in still water
= (7.2 + 2.4) kmph
= 9.6 kmph
$\therefore$ Rate downstream of the boat
= (9.6 + 2.4) kmph
= 12 kmph
$\therefore$ Time taken in covering 78 km distance
$=\frac{78}{12}$
= 6.5 hours or 6 hour 30 minutes.
