Latitudianal difference=(10+70)=80
So, time difference=80X4=320mins=5 hrs 20 mins
Since the place is located towards west
Therefore local time of that place during take off=8:40 p.m.
So, local time during landing=8:40p.m.+10hrs=6:40a.m.
Latitude change = (10 + 70 ) = 80 degrees
1 degree change corresponds to 4 min difference
So total time difference = 80 * 4 = 320 min
= 5 hrs 20 mins
In going from east to west , time decreases
Local time = 2 am + 10 – 5hr 20 min
= 6.40 am
6.40 am
