Mis amigos fueron a Atlanta ______ una carro. por or para

It is incorrect to use either "por" or "para" in this sentence. The correct preposition to use is "en". The correct sentence would be "Mis amigos fueron a Atlanta en carro".

but somehow i have to choose one

If you have to choose between "por" or "para" only, "por" would be a better choice as it implies transportation by means of a vehicle. However, it's important to note that "en" is the most appropriate preposition to use in this sentence.

can i use "en" and "por"

No, you cannot use both "en" and "por" in this sentence. The correct preposition to use is "en", which indicates the means of transportation that your friends used to get to Atlanta. So the correct sentence is "Mis amigos fueron a Atlanta en carro".
