You have traveled from 70 deg E of the Prime Meridian to 70 deg W. That means you have traveled 140 degrees west. (The north-south component of your travel doesn't affect the time.)
Each time zone is 15 degrees wide (360 degrees divided by 24 hours equals "15 degrees per hour," meaning 15 degrees per time zone). Actually, that is an idealization, since almost every time zone line has some zigzags in it rather than running exactly north and south. For simplicity, we'll assume that the time zone lines are straight (i.e., they are "meridians").
By going 140 degrees west, you have moved to a place where it is 9 1/3 hours earlier (140 / 15 = 9 1/3). Depending on exactly where you started within the first time zone, you may have changed time zones either 9 or 10 times, so it is either 9 or 10 hours earlier than the current time at your point of origin.
At your point of origin, it is 2:00AM plus 10 hours when you land, so it is noon. The local time where you land is either 9 or 10 hours earlier, so it is either 2:00 or 3:00AM. (If you're using "sun time" instead of "standard time" based on time zones, the local time would be exactly 2:40AM.)
P.S. Why didn't you use 75E and 75W in your problem? Then the local time at your destination would definitely have been 2:00AM, the same as your departure time.

Welllllllllllllll it is a very nice question which i think is very difficult to ask but easy to answer.
Well the answer is simple logic and isssssssssssss
The local time will be around quater to 2.00 AM.
I used simple logic that for every 15 degrees there will be 1 hour difference. You travelled 14 degrees to west. So by calculations i figured that when you sat on the plane the localtime of your location was 3:45 pm and you and you travelled 10 hours therefore the localtime 1:45 AM. Asta la vista baby

Since the difference in time between E and west is of three hours
therefore time will be 9.00 P.M.
