1 degree=4 minutes
since local time difference depends on longitude only, total degrees travelled=10 deg E+70 deg W=80 deg
total time difference=80*4=320 minutes=5 hours 20 minutes
time of journey=10 hours
local time at A 6 am + 10 hrs - time diff (aircraft is travelling west)
local time at B=10.40am
