Time zone worksheet for learning about U.S. time zones using a map and real-world scenarios.

Problem: Solve the time zone questions using the provided map and explanation.

#### Key Information from the Map:
- The United States is divided into four main time zones:
1. Pacific Time (PT): 3 hours behind Eastern Time (ET).
2. Mountain Time (MT): 2 hours behind Eastern Time (ET).
3. Central Time (CT): 1 hour behind Eastern Time (ET).
4. Eastern Time (ET): Reference time zone.

#### Steps to Solve Each Question:

Question 1: If it is 5:00 p.m. in New York City, what time is it in St. Louis?

- New York City is in the Eastern Time Zone (ET).
- St. Louis is in the Central Time Zone (CT), which is 1 hour behind ET.
- If it is 5:00 p.m. in New York City (ET), then in St. Louis (CT), it will be:
$$
5:00 \, \text{p.m.} - 1 \, \text{hour} = 4:00 \, \text{p.m.}
$$

Answer: 4:00 p.m.

Question 2: If it is 9:30 p.m. in San Francisco, what time is it in Atlanta?

- San Francisco is in the Pacific Time Zone (PT).
- Atlanta is in the Eastern Time Zone (ET).
- The difference between PT and ET is 3 hours (PT is 3 hours behind ET).
- If it is 9:30 p.m. in San Francisco (PT), then in Atlanta (ET), it will be:
$$
9:30 \, \text{p.m.} + 3 \, \text{hours} = 12:30 \, \text{a.m.} \, (\text{next day})
$$

Answer: 12:30 a.m.

Question 3: Imagine you're in New Orleans, and your friend in Denver asked you to call at 4:00 p.m. What time should you call them?

- New Orleans is in the Central Time Zone (CT).
- Denver is in the Mountain Time Zone (MT).
- The difference between CT and MT is 1 hour (CT is 1 hour ahead of MT).
- If your friend wants you to call at 4:00 p.m. in Denver (MT), you should call them at:
$$
4:00 \, \text{p.m.} - 1 \, \text{hour} = 3:00 \, \text{p.m.}
$$

Answer: 3:00 p.m.

Question 4: Pretend you're flying from Cleveland to Salt Lake City. It's a four-hour flight, and you leave at 8:00 a.m. What time will it be in Salt Lake City when you land?

- Cleveland is in the Eastern Time Zone (ET).
- Salt Lake City is in the Mountain Time Zone (MT).
- The difference between ET and MT is 2 hours (MT is 2 hours behind ET).
- If you leave Cleveland at 8:00 a.m. (ET) and the flight takes 4 hours, you will arrive in Salt Lake City at:
$$
8:00 \, \text{a.m.} + 4 \, \text{hours} = 12:00 \, \text{p.m.} \, (\text{noon}) \, \text{(in ET)}.
$$
- Convert this time to Mountain Time (MT):
$$
12:00 \, \text{p.m.} \, (\text{ET}) - 2 \, \text{hours} = 10:00 \, \text{a.m.} \, (\text{MT}).
$$

Answer: 10:00 a.m.

Question 5: Pretend you're flying from Los Angeles to Boston. It's a six-hour flight, and you leave at 1:30 a.m. What time will it be in Boston when you land?

- Los Angeles is in the Pacific Time Zone (PT).
- Boston is in the Eastern Time Zone (ET).
- The difference between PT and ET is 3 hours (ET is 3 hours ahead of PT).
- If you leave Los Angeles at 1:30 a.m. (PT) and the flight takes 6 hours, you will arrive in Boston at:
$$
1:30 \, \text{a.m.} + 6 \, \text{hours} = 7:30 \, \text{a.m.} \, (\text{in PT}).
$$
- Convert this time to Eastern Time (ET):
$$
7:30 \, \text{a.m.} \, (\text{PT}) + 3 \, \text{hours} = 10:30 \, \text{a.m.} \, (\text{ET}).
$$

Answer: 10:30 a.m.

Question 6: A train ride from Atlanta to Dallas is 18 hours. If you left Atlanta at 8:00 a.m., what time will it be when you arrive in Dallas?

- Atlanta is in the Eastern Time Zone (ET).
- Dallas is in the Central Time Zone (CT).
- The difference between ET and CT is 1 hour (CT is 1 hour behind ET).
- If you leave Atlanta at 8:00 a.m. (ET) and the train ride takes 18 hours, you will arrive in Dallas at:
$$
8:00 \, \text{a.m.} + 18 \, \text{hours} = 2:00 \, \text{a.m.} \, (\text{next day in ET}).
$$
- Convert this time to Central Time (CT):
$$
2:00 \, \text{a.m.} \, (\text{ET}) - 1 \, \text{hour} = 1:00 \, \text{a.m.} \, (\text{CT}).
$$

Answer: 1:00 a.m.
