Step-by-step solution for: Time Zones online exercise
To solve these problems, we need to use the time zone map provided. The map shows different cities and their corresponding time zones relative to Greenwich (which is at 0). By looking at the colored bands and the numbers at the bottom, we can figure out how many hours ahead or behind each city is compared to Greenwich.
Let's break down each question step by step:
1. If it is 1 p.m. in Greenwich. What time is it in Los Angeles?
* Find Greenwich: Look at the map for "Greenwich". It is in the center column labeled "noon" at the top and "+0" at the bottom.
* Find Los Angeles: Look for "Los Angeles" on the left side of the map (United States).
* Determine the time difference: Follow the column down from Los Angeles to the bottom row of numbers. It aligns with the number -8. This means Los Angeles is 8 hours behind Greenwich.
* Calculate the time: Start with 1 p.m. (which is 13:00). Subtract 8 hours.
* 13:00 - 8 hours = 5:00.
* Determine a.m. or p.m.: Since 5:00 is in the morning, it is 5 a.m.
2. If it is 3 p.m. in Greenwich. What time is it in Moscow?
* Find Moscow: Look for "Moscow" on the map (Russia).
* Determine the time difference: Follow the column down from Moscow. It aligns with the number +3. This means Moscow is 3 hours ahead of Greenwich.
* Calculate the time: Start with 3 p.m. (which is 15:00). Add 3 hours.
* 3 p.m. + 3 hours = 6 p.m.
3. If it is 5 p.m. in Greenwich. What time is it in New Delhi?
* Find New Delhi: Look for "New Delhi" on the map (India).
* Determine the time difference: Follow the column down from New Delhi. It aligns with the number +5. This means New Delhi is 5 hours ahead of Greenwich.
* Calculate the time: Start with 5 p.m. (which is 17:00). Add 5 hours.
* 5 p.m. + 5 hours = 10 p.m.
4. If it is 7 p.m. in Greenwich. What time is it in New York?
* Find New York: Look for "New York" on the map (United States).
* Determine the time difference: Follow the column down from New York. It aligns with the number -5. This means New York is 5 hours behind Greenwich.
* Calculate the time: Start with 7 p.m. (which is 19:00). Subtract 5 hours.
* 7 p.m. - 5 hours = 2 p.m.
5. If it is 9 p.m. in Greenwich. What time is it in Perth?
* Find Perth: Look for "Perth" on the map (Australia).
* Determine the time difference: Follow the column down from Perth. It aligns with the number +8. This means Perth is 8 hours ahead of Greenwich.
* Calculate the time: Start with 9 p.m. (which is 21:00). Add 8 hours.
* 9 p.m. + 8 hours = 17 hours past midnight? No, let's count: 9 + 8 = 17.
* Wait, let's re-calculate carefully. 9 p.m. is 21:00.
* 21:00 + 8 hours = 29:00.
* Since a day has 24 hours, we subtract 24 to find the next day's time.
* 29 - 24 = 5.
* So the time is 5:00 the next morning.
* Determine a.m. or p.m.: Since 5:00 is in the morning, it is 5 a.m.
Final Answer:
1. 5 a.m.
2. 6 p.m.
3. 10 p.m.
4. 2 p.m.
5. 5 a.m.
