downstream speed =20/2=10 km/h
upstream speed=4/2=2 km/h
difference=10-2=8 km/hr
means speed in still water =6 km/h
and speed of current =4 km/h
then,speed of boat in upstream =6+4=10 km/h
and in downstream=6-4=2km/h
upstream speed=4/2=2 km/h
difference=10-2=8 km/hr
means speed in still water =6 km/h
and speed of current =4 km/h
then,speed of boat in upstream =6+4=10 km/h
and in downstream=6-4=2km/h
