As we know that 1 deg =4 min.
and latitude change=(10+70)=80(That flight at 2 am making 10 deg with north and after 10 hrs ,it is making 70 deg with north.)
therefore,80 deg=(80*4)mins
=320 mins.
=5hrs 20 mins.
local time difference between source and destination place=5 hrs 20 mins
hence,after 10 hrs ,according to a person ,it should be 12 pm.
but local time at that place=12 pm-5 hrs 20 mins
=6 am 40 mins.
