Depends on how fast you can swim. Not enough information.
If you assume to frictional force from the water's viscosity,
Time(h) :12km / [(your velocity in km/h) - 6]

If you move upstream at near the speed of light, it will be nearly instantaneous. At lower speeds, the increase in time is directly proportional to the decrease in speed and approaches infinity as you reach 6 km/h and lower.

That would depend how fast you are moving. If you meant downstream, then it would take 2 hours moving at 6 km/h.

Move upstream 12 km at what speed?????? Even the joker who told you he/she is good at math blew it.

in one course it somewhat is further to boat's velocity, interior different the present and boat wrestle. the version in distance is 13 km. devoid of present day-day, the trip distances might desire to be comparable, (7+6.5) = (20-6.5). If the boat grew to alter into into no longer under potential, it would desire to go with the flow downstream the 6.5Km in the time it took to do one leg of the trip. what isn't stated on your question is what volume hours to make that 6.5Km distance. in basic terms then can the cost of the present be figured.

It will take forever.
In fact you'll never get there if your going to the wrong direction.
Good luck!
