If you live in Atlanta and your grandparents live in Seattle. What is the latest Atlanta time you would expect to hear from them if they go to bed at 10 pm?
Atlanta, Georgia, is in the Eastern Time Zone, while Seattle, Washington, is in the Pacific Time Zone. Since Atlanta is three hours ahead of Seattle, when it's 10 p.m. in Seattle, it's 1 a.m. the next day in Atlanta.

What is the answer to the above question
To determine the latest Atlanta time you would expect to hear from your grandparents in Seattle if they go to bed at 10 pm, you need to account for the time difference between the two cities.
As mentioned earlier, Atlanta is three hours ahead of Seattle. So, if your grandparents in Seattle go to bed at 10 pm Pacific Time, it would be 1 am the next day in Atlanta Eastern Time.
Therefore, the latest Atlanta time you would expect to hear from them if they go to bed at 10 pm in Seattle would be around 1 am Eastern Time.
