Question

WHEN it is 9am at Station A (140°E), what is
the local time in Station B (20 °E) ?​

Answer 1

Answer:

Let me explain.

The station A is at 60° West with local time 6:30 PM.

Station B has local time 4:30 PM.

Now,we can find that the time difference between the two stations is two hours.

Since 15° is covered in one hour, in the same way 2 hours would cover 30°.

Simply add 30 degrees to station A location i.e 60°.The answer would be 90°.

It's direction would be towards East of the Station A because station B is ahead of station A in time.

So it would be 90° West.
