You can put this solution on YOUR website! .
The entire round trip lasted 3 hours + 6 hours = 9 hours, as described in the condition.
At no wind, the round trip will take 6 + 6 = 12 hours, PROBABLY.
If you (or somebody else) will disprove this solution, I will say that in a way it is formulated, it is NOT a Math problem at all.

If there's no wind, a hot-air balloon would remain stationary over the starting point.
