Question

if the time at GMT is 1pm, what will be the time at 45 degrees west and east

Answer 1

Longitudinal difference of the places from GM
=45 degrees
Well ,we know that
1 degrees of longitudinal difference results in 4 mins of time difference.
therefore, time difference of the place from GMT = 45 * 4 min
= 180 min
= 3 hrs
Now,
On going east u gain time,
So, time of the place 45 ° east
= 1 pm + 3 hrs
= 13 hrs + 3 hrs
= 16 hrs
=4 pm

Similarly,
In 45 degrees west, it is
1 pm - 3 hrs
= (13-3) hrs
=10 hrs
= 10 am

So ultimate
on 45° east it is 4 pm
on45° west it is 10 am
both the same day

Answer 2

on 45° east it is 4 pm

on45° west it is 10 am
