To find time of a place you can use Google as online time clock, but to solve it manually go below.
Q1:If the time is 8 PM on thursday at station A(120°E ) what is the time at station B 120°W).
Solution: Difference of longitude between station A and station B =120°+120°=240°
We know,
1 degree longitude to 1 degree longitude the time difference = 4 minutes
For 240 degree longitude the time difference=240×4=960'
=960÷60=16 hours
Station B is situated at West of station A therefore time of station B will be 16 hour behind the time of station A.
That means the time of station a will be 4 AM.
Actually what we did orally is very simple. We first counted backwards 8 hours and reached at 12 noon after that again we counted 8 hours backward and we reached at 4 a m. Isn't it very simple.

=124÷60=2 hours 4 minutes
