​

Answer 1

Answer:

1. The Earth rotates through 15° each hour so to rotate through 30° degrees it would take 2 hours.

2. 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.
