Final answer:
At 12:00 am in Indiana, it is also 12:00 am in eastern Michigan since both locations share the Eastern Standard Time zone. At 9:00 am in eastern Nebraska, it is 8:00 am in Utah as Nebraska is in the Central Time Zone and Utah is in the Mountain Time Zone, which is one hour behind.
Step-by-step explanation:
If it is 12:00 am in Indiana, the time in eastern Michigan is also 12:00 am. Both Indiana and eastern Michigan are in the Eastern Standard Time zone, which is five hours behind the time at the prime meridian, known as Universal Time (UT).
When it is 9:00 am in eastern Nebraska, the time in Utah is 8:00 am. Nebraska is in the Central Time Zone, and Utah is in the Mountain Time Zone, which is one hour behind Central Time. It's essential to note the fact that Pacific standard time is 3 hours earlier than Eastern standard time. With Eastern Time Zone and Mountain Time Zone between these two standards, one can establish the one-hour time difference between Nebraska and Utah.
The United States is divided into several time zones: Eastern, Central, Mountain, and Pacific primarily. This system helps keep time standardized across different regions, considering the Earth's rotation and time advancing towards the east.
