Answer:
Call her 5pm on Tuesday
Step-by-step explanation:
The problem here is that Manila and Chicago are in different time zones.
To solve this, we must convert Manila time to Chicago time.
Manila is 14hrs ahead of Chicago;
Manila is the capital city of the Philippines located in Asia. Chicago is a city in the United States of America.
As with regions with different longitudes on the earth surface, there would be differences between their time zones. This is because the earth is a spherical body. Some places are ahead whereas, some others are behind.
Manila is 14hrs ahead of Chicago
To call her at 9am Manila time from Chicago;
Simply Subtract 9 hrs from 14hrs which gives 5pm the previous day.
Call her 5pm on Tuesday
