TRAVEL TIME QUESTION? LONDON TO NEW YORK?

[NeedingAnswersBadly]

Okay, I know that New York is five hours behind London. The shortest flight time from London Heathrow Airport to JFK New York Airport is approx. 7hrs and 25 mins.

So, what time would I arrive in New York if I left London at 10:30pm?

Please help and thanks so much!
