Final answer:
The time for your friend, who lives 30°W of you, would be 10:00 AM.
Step-by-step explanation:
To determine the time for your friend who lives 30°W of you, you need to know the time difference between your location and the prime meridian (0°W). According to the information provided, 15° to the west of your location corresponds to 11 a.m. So, 30° west of your location would be two times that, which is 22 a.m. or 10 a.m. Since it is 5:00 PM your time, the time for your friend would be 10:00 AM.
