Town Y = 60°W
Procedures:
A. Locate the places involved
B. Find the time difference
C. Convert the time difference to longitude
D. Adjust the longitude to the direction of movement (west or east)
A. 8am comes before 2pm
So Town Y is in West
B. 8—2 = 6hrs
C. Since 15° = 1hr
6 × 15 = 90°
D. Since the Town Y is in West, we subtract 90° from 30°E.
90° — 30° = 60°W
Therefore, the longitude of town Y= 60°W
