My flight takes of at 2pm from a place at 18N 40E and landed 10 Hrs
later at a place with coordinates 36N40W. What is the local time when
my plane landed?

1. 8.00pm 2. 6.00pm 3. 12.00am 4. 6.40pm

• Answer is 6:40
  
  As difference betweenn longitude is of 80 degree.
  
  For 1 degree there is difference of 4 min
  
  so for 80 deg, diff is of 320 mins=4:40hrs
  
  add 10hrs to 4.40
  
  and then add this to 2:00Am
  
  U will get 6:40 am

  first ignore the 18N and 36N on your coordinates. The latitude(north-south) have nothing to do with time zones.
  
  So we have 40 East to 40 West. Obviously you are flying from east to west over the Prime Meridian which is considered the centre or 0 degrees. Thats a total of 80 Degrees travelled.
  
  The world is 360 degrees around and it is divided into 24 timezones of one hour each. Take 360 degrees and divide by 24 and you get 15 degrees. So now we know that every time zone or an hour difference is equal to 15 degrees of movement on globe. Remember this, it will come in handy at some point in your life.
  
  Since you actually travelled 80 degrees in total: take 80 degrees and divide it by 15 degrees you get 5.333333.
  
  This is how many hours difference there is from 40E to 40W. Simplified thats 5 hours and 20 minutes (.3333 x 60 = 20min).
  
  Because the sun travels east to west; when it was 2 pm at 18N 40E, it was actually 8:40 am, earlier on the same day at 36N 40W .
  
  Since the flight took 10 hours you landed at 6:40 pm local time on the 36N40W coordinates.

• Ignore the north and the difference between east and west longitude will be counted,
  
  As difference between longitude is of (40-(-40)= 80) 80 degree.
  
  For 1 degree there is difference of 4 min
  
  so for 80 deg, diff is of 320 mins
  which is = 5hr :20 mins
  
  as we are travelling from east to west , time decreases i.e.,
  10hrs-5 hr:20 mins= 4hrs:40 mins
  
  as we started from 2pm we will lad at 2pm+ 4hrs:40mins= 6hrs:40mins
