Try yourself:My flight took off at 2 am from a place at 18N 10E and landed 10 hours later at a place with coordinates 36N 70W. What is the local time when my plane landed?
Explanation
Local time varies only with longitudes.
The flight travelled from 10E to 70W longitudes i.e. 80° longitudes.
Time change because of longitude change = 80 × 4 = 320 minutes = 5 hours and 20 minutes
Time at 18N 10E after 10 hour journey = 2 am + 10 hours = 12 pm
Because the flight travelled towards West from East, the local time at 36N 70W
= 12 pm - 5 hrs 20 m = 6:40 am
