longitudinal difference=10+70=80 degree.1 degree change=4 min time difference so 80 degree=320 min so going from east to west decrease in local time (2+10-5 hr 20 min)=6.40 a.m

Remember, while moving from east to west countries lag in time. Remember when Test cricket starts in England? 3. 30 in afternoon. Right? ie., We are in after noon means they are in morning.
If the coordinates change from 10 E to 70W, the plane has moved a total of 80 degrees. We know that with each degree time increases by 4 minutes while going from east to west. (How? 24 x 60 min / 360 degrees, So 1 degree = 4 min)
So total time change = 4 x 80 = 320 min = 5 hrs + 20 minutes.
After 10 hours local time is (2 am + 10 - 5.20 hrs) = 6.40 AM.
