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)

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
