Identify time zone relationships

The map shows four US time zones:

• Pacific (purple): Leftmost zone.
• Mountain (orange): 1 hour ahead of Pacific.
• Central (blue): 2 hours ahead of Pacific, 1 hour ahead of Mountain.
• Eastern (red): 3 hours ahead of Pacific, 2 hours ahead of Mountain, 1 hour ahead of Central.

Solve Question 1

• Given: 2:00 p.m. in Washington, DC (Eastern Zone).
• Target: Time in Alabama (Central Zone).
• Calculation: Central is 1 hour behind Eastern.

$$ 2:00\text{ p.m.} - 1\text{ hour} = 1:00\text{ p.m.} $$

Solve Question 2

• Given: Noon (12:00 p.m.) in California (Pacific Zone).
• Target: Time in Wyoming (Mountain Zone).
• Calculation: Mountain is 1 hour ahead of Pacific.

$$ 12:00\text{ p.m.} + 1\text{ hour} = 1:00\text{ p.m.} $$

Solve Question 3

• Given: 9:00 a.m. in Montana (Mountain Zone).
• Target: Time in Iowa (Central Zone).
• Calculation: Central is 1 hour ahead of Mountain.

$$ 9:00\text{ a.m.} + 1\text{ hour} = 10:00\text{ a.m.} $$

Solve Question 4 & 5

• Question 4 Given: 6:00 p.m. in North Carolina (Eastern Zone).
• Question 4 Target: Time in Colorado (Mountain Zone).
• Question 4 Calculation: Mountain is 2 hours behind Eastern.

$$ 6:00\text{ p.m.} - 2\text{ hours} = 4:00\text{ p.m.} $$

• Question 5 Given: 1:00 p.m. in Maine (Eastern Zone).
• Question 5 Target: Time in Nevada (Pacific Zone).
• Question 5 Calculation: Pacific is 3 hours behind Eastern.

$$ 1:00\text{ p.m.} - 3\text{ hours} = 10:00\text{ a.m.} $$
