To solve the problem, we need to use the time zone map provided in the image. The map shows the time differences between Greenwich (which is at UTC+0) and other cities around the world. Let's go through each question step by step:
1. If it is 1 p.m. in Greenwich, what time is it in Los Angeles?
-
Greenwich is at UTC+0.
-
Los Angeles is at UTC-8.
- To find the time in Los Angeles when it is 1 p.m. in Greenwich:
- Subtract 8 hours from 1 p.m.: \( 1 \text{ p.m.} - 8 \text{ hours} = 5 \text{ a.m.} \).
Answer: 5 a.m.
---
2. If it is 3 p.m. in Greenwich, what time is it in Moscow?
-
Greenwich is at UTC+0.
-
Moscow is at UTC+3.
- To find the time in Moscow when it is 3 p.m. in Greenwich:
- Add 3 hours to 3 p.m.: \( 3 \text{ p.m.} + 3 \text{ hours} = 6 \text{ p.m.} \).
Answer: 6 p.m.

3. If it is 5 p.m. in Greenwich, what time is it in New Delhi?
-
Greenwich is at UTC+0.
-
New Delhi is at UTC+5:30.
- To find the time in New Delhi when it is 5 p.m. in Greenwich:
- Add 5 hours and 30 minutes to 5 p.m.: \( 5 \text{ p.m.} + 5 \text{ hours} + 30 \text{ minutes} = 10:30 \text{ p.m.} \).
Answer: 10:30 p.m.

4. If it is 7 p.m. in Greenwich, what time is it in New York?
-
Greenwich is at UTC+0.
-
New York is at UTC-5.
- To find the time in New York when it is 7 p.m. in Greenwich:
- Subtract 5 hours from 7 p.m.: \( 7 \text{ p.m.} - 5 \text{ hours} = 2 \text{ p.m.} \).
Answer: 2 p.m.
---
5. If it is 9 p.m. in Greenwich, what time is it in Perth?
-
Greenwich is at UTC+0.
-
Perth is at UTC+8.
- To find the time in Perth when it is 9 p.m. in Greenwich:
- Add 8 hours to 9 p.m.: \( 9 \text{ p.m.} + 8 \text{ hours} = 5 \text{ a.m.} \) (next day).
Answer: 5 a.m.
---
Final Answers:
1. If it is 1 p.m. in Greenwich, it is
5 a.m. in Los Angeles.
2. If it is 3 p.m. in Greenwich, it is
6 p.m. in Moscow.
3. If it is 5 p.m. in Greenwich, it is
10:30 p.m. in New Delhi.
4. If it is 7 p.m. in Greenwich, it is
2 p.m. in New York.
5. If it is 9 p.m. in Greenwich, it is
5 a.m. in Perth.
Boxed Final Answer:
\[
\boxed{
\begin{array}{ll}
\text{1. } & 5 \text{ a.m.} \\
\text{2. } & 6 \text{ p.m.} \\
\text{3. } & 10:30 \text{ p.m.} \\
\text{4. } & 2 \text{ p.m.} \\
\text{5. } & 5 \text{ a.m.}
\end{array}
}
