Find the long of town y whose time is 8am when the time of another town x (long 30°e)is 2pm the same day
Thank you
Solve it out with explaination
If the longitude of a town y whose time is 8am when the time of another town ×(longitude30°e) is 2pm the same
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
