I have a friend leaving croatia and is do back Sept.12 in seattle washington at 6:00pm. What time does he leave croatia?
Your kidding ? Right ?? When his plane leaves the ground.
Matt, it's impossible to provide an answer to your question without more specific information. For example, is his flight a direct flight from Croatia, or does he have a connection in Frankfurt or other "hub"? His flight will probably be AT LEAST 12-13 hours. Cheers!
Are you trying to make us do your math homework for you? This looks like one of those vague work problems, good luck! If your friend wants you to pick him up, I sure hope he provides you with better details :-}
