{'noon': [0, 0, 4, 2], 'hours': [7, 2, 16, 9], 'time': [2, 6, 15, 23], 'city': [20, 2, 8, 20]}

The question asks about the time in a city located on 105° W longitude when it is 12 noon in a city on 90° W longitude. To solve this, we need to remember that the Earth rotates 360° in 24 hours, which means it rotates 15° per hour.

Since the city on 90° W longitude is located 15° to the east of the city on 105° W longitude, it would be ahead in time. Therefore, the correct option would be the one with an earlier time than 12 noon.

Option 1 (13:00 hours) is incorrect because it would mean the city to the west is 1 hour ahead of the city to the east, which is not the case.

Option 2 (12:30 hours) is incorrect because it would mean the city to the west is 30 minutes ahead of the city to the east, which is not the case.

Option 3 (11:30 hours) is incorrect because it would mean the city to the west is 30 minutes behind the city to the east, which is not the case.

Option 4 (11:00 hours) is correct because it represents an earlier time, indicating that the city on 105° W longitude is
