The velocity of boat = 12Km/hr.
During moving against water resultant velocity be = V current - V boat
=12/3
=4 Km/hr.
VCurrent-V boat = 4
V current-12= 4
V current=16 km/hr.
During moving against water resultant velocity be = V current - V boat
=12/3
=4 Km/hr.
VCurrent-V boat = 4
V current-12= 4
V current=16 km/hr.

Let the speed of the current = x km/h
According to the question,
= 12 - 4 = x = 8 km/h
DistanceTime=121=12km/h

Speed of boat in still water:
distance/time = 12/1 =12km/hr
Speed against the current =
12/3=4 km/hr
Let the speed of the current = x km/h
According to the question,
= 12 - 4 = x = 8 km/h
According to the question,
= 12 - 4 = x = 8 km/h
This is the ans
please add this as brainliest
please .....and sorry for the inconvenience
