1. You have figured out where you are.
2. You have checked in.
3. You are on EST.
4. You are embarrased about your math skills and are seriously in jeopardy of losing the n part of hn as a result.....
That is so funny! But you didn't address the differential.
Actually, I did a lot of rounding to make it easier for you. Plane actually left at 7:30, flight took 5 hr.
Do I get to keep the h part anyway? I have cash.
