All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad, sallallaahu`alayhi wa sallam, is His slave and Messenger.
If you were fasting during your aforementioned travel, then you break your fast at the time the sun sets in the place where you are in, whether the sun sets while you are traveling or after your arrival. The traveler begins and ends his fast according to the place in which he is, so he begins his fast at dawn in the place in which he is in and he breaks his fast when the sun sets in the place where he is. So if the sun has not set yet in the place you are in, do not break your fast based on its setting in the country from which you traveled from or the country to which you have not reached yet, because what counts is that it sets on you in the place where you actually are in.
Allah knows best.
