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.
