Final answer:
When it is 9:00 am in Texas, it is 10:00 am in Ohio because Ohio is one hour ahead of Texas, which is in the Central Time Zone.
Step-by-step explanation:
If Chance calls from Texas to Ohio at 9:00 am, we need to consider the time zones that are in effect in both states. Texas is primarily in the Central Time Zone, while Ohio is in the Eastern Time Zone. Due to this, Ohio is one hour ahead of Texas.
Therefore, if it is 9:00 am in Texas, it is 10:00 am in Ohio. Remember, this is assuming that Chance is calling from an area in Texas that is within the Central Time Zone, as some parts of Texas are in the Mountain Time Zone, which would introduce a different time difference.
