Answer 2

Answer:

The answer would be 90° West.

How?

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.
