Final answer:
When it is midnight in Chicago, it is 10 p.m. the previous day in Seattle because Seattle is 2 hours behind Chicago in the Pacific Time Zone.
Step-by-step explanation:
Chicago and Seattle are in different time zones. Chicago is in the Central Time Zone, whereas Seattle is in the Pacific Time Zone. Since Seattle is west of Chicago, you subtract hours from Chicago’s time to determine the time in Seattle. The Pacific Time Zone is 2 hours behind the Central Time Zone.
If it is midnight (12:00 a.m.) in Chicago, you would subtract 2 hours to find out the time in Seattle. Therefore, the correct answer is 10 p.m. the previous day in Seattle when it's midnight in Chicago.
