Answer:
Step-by-step explanation:
Time at Greenwich = 7:30 pm
Greenwich is the 0° meridian of longitude.
Time at given place = 12 pm
Difference between the time at both places = 7 hours 30 mins.
NOW, as the time at given place is LESS than that at the Greenwich meridian, the place is to the WEST of it.
1° = interval of 4 mins
Therefore, 15° = 1 hour
Now, X° = 7.5 hours
-> 15 × 7.5 = 7.5 hours
-> 112.5° WEST
