WORKSHEET : TIME ZONE online exercise for - Free Printable

Let's solve the World Time Zones Worksheet step by step using the provided map.

---

Step 1: Understand the Map

- The map shows time zones in different colors.
- Each color represents a time zone, with UTC offsets (e.g., UTC+5, UTC-3).
- The Prime Meridian (UTC+0) runs through Greenwich, London.
- Times are written in 24-hour format (e.g., 9:00 AM = 0900, 6:30 PM = 1830).

We will use the UTC offset for each city to calculate time differences.

## ✔ Question 1: If it is 9:00 AM in Bangkok, what time is it in the following locations?

Bangkok is in UTC+7 (from the map — Thailand is marked as +7).

So we convert 9:00 AM = 0900 in Bangkok (UTC+7).

Now subtract or add the difference from each location:

| City | UTC Offset | Time Difference from Bangkok | Calculation | Local Time |
|-------------|------------|-------------------------------|-------------|------------|
| Istanbul | UTC+3 | -4 hours | 0900 - 4 = 0500 | 0500 (5:00 AM) |
| Los Angeles | UTC-8 | -15 hours | 0900 - 15 = -6 → Add 24 → 1800 | 1800 (6:00 PM) |
| Perth | UTC+8 | +1 hour | 0900 + 1 = 1000 | 1000 (10:00 AM) |
| Paris | UTC+1 | -6 hours | 0900 - 6 = 0300 | 0300 (3:00 AM) |
| Delhi | UTC+5.5 | -1.5 hours | 0900 - 1.5 = 0730 | 0730 (7:30 AM) |
| Sao Paulo | UTC-3 | -10 hours | 0900 - 10 = -1 → Add 24 → 2300 | 2300 (11:00 PM) |
| Moscow | UTC+3 | -4 hours | 0900 - 4 = 0500 | 0500 (5:00 AM) |
| New York | UTC-5 | -12 hours | 0900 - 12 = -3 → Add 24 → 2100 | 2100 (9:00 PM) |

> ✔ Answer 1:
> - Istanbul: 0500
> - Los Angeles: 1800
> - Perth: 1000
> - Paris: 0300
> - Delhi: 0730
> - Sao Paulo: 2300
> - Moscow: 0500
> - New York: 2100

## ✔ Question 2: If the time in Sydney is 6:30 PM, what time is it in the following locations?

Sydney is in UTC+10 (map shows Australia at +10).

6:30 PM = 1830 in Sydney (UTC+10)

We'll compute time in other cities relative to UTC+10.

| City | UTC Offset | Time Difference from Sydney | Calculation | Local Time |
|--------------|------------|------------------------------|-------------|------------|
| Oslo | UTC+2 | -8 hours | 1830 - 8 = 1030 | 1030 (10:30 AM) |
| Auckland | UTC+12 | +2 hours | 1830 + 2 = 2030 | 2030 (8:30 PM) |
| Cape Town | UTC+2 | -8 hours | 1830 - 8 = 1030 | 1030 (10:30 AM) |
| Hong Kong | UTC+8 | -2 hours | 1830 - 2 = 1630 | 1630 (4:30 PM) |
| Cairo | UTC+2 | -8 hours | 1830 - 8 = 1030 | 1030 (10:30 AM) |
| San Francisco| UTC-8 | -18 hours | 1830 - 18 = 030 → Add 24 → 0300 | 0300 (3:00 AM) |
| Toronto | UTC-5 | -15 hours | 1830 - 15 = 0330 → Add 24 → 0330 | 0330 (3:30 AM) |
| London | UTC+0 | -10 hours | 1830 - 10 = 0830 | 0830 (8:30 AM) |

> ✔ Answer 2:
> - Oslo: 1030
> - Auckland: 2030
> - Cape Town: 1030
> - Hong Kong: 1630
> - Cairo: 1030
> - San Francisco: 0300
> - Toronto: 0330
> - London: 0830

## ✔ Question 3: Flight departs Tokyo at 3:30 PM (1530). What is the arrival local time?

Tokyo is in UTC+9.

We’ll:
1. Add flight time to departure time (in Tokyo time)
2. Convert to local time of destination using their UTC offset

---

✔ Flight to Vancouver (8:45 hours)

- Departure: 1530 (Tokyo, UTC+9)
- Flight time: 8h 45m
- Arrival in Tokyo time: 1530 + 8:45 = 2415 → 0015 next day (1:15 AM)
- Vancouver is UTC-8
- Time difference: UTC+9 to UTC-8 = 17 hours behind
- So: 0015 - 17 = -16:45 → Add 24 → 07:15
- Arrival in Vancouver: 0715 (7:15 AM)

> ✔ Vancouver: 0715

---

✔ Flight to Honolulu (7:20 hours)

- Departure: 1530 (Tokyo)
- Flight time: 7h 20m
- Arrival in Tokyo time: 1530 + 7:20 = 2250
- Honolulu is UTC-10
- Difference: UTC+9 to UTC-10 = 19 hours behind
- 2250 - 19 = 0350
- Arrival in Honolulu: 0350 (3:50 AM)

> ✔ Honolulu: 0350

---

✔ Flight to New York (12:40 hours)

- Departure: 1530 (Tokyo)
- Flight time: 12h 40m
- Arrival in Tokyo time: 1530 + 12:40 = 2810 → 0410 next day
- New York is UTC-5
- Difference: UTC+9 to UTC-5 = 14 hours behind
- 0410 - 14 = -09:50 → Add 24 → 1410
- Arrival in New York: 1410 (2:10 PM)

> ✔ New York: 1410

---

✔ Flight to Rome (14:45 hours)

- Departure: 1530 (Tokyo)
- Flight time: 14h 45m
- Arrival in Tokyo time: 1530 + 14:45 = 3015 → 0615 next day
- Rome is UTC+1
- Difference: UTC+9 to UTC+1 = 8 hours behind
- 0615 - 8 = -01:45 → Add 24 → 2215
- Arrival in Rome: 2215 (10:15 PM)

> ✔ Rome: 2215

---

✔ Flight to Manila (5 hours)

- Departure: 1530 (Tokyo)
- Flight time: 5h
- Arrival in Tokyo time: 1530 + 5 = 2030
- Manila is UTC+8
- Difference: UTC+9 to UTC+8 = 1 hour behind
- 2030 - 1 = 1930
- Arrival in Manila: 1930 (7:30 PM)

> ✔ Manila: 1930

---

✔ Flight to Moscow (10 hours)

- Departure: 1530 (Tokyo)
- Flight time: 10h
- Arrival in Tokyo time: 1530 + 10 = 2530 → 0130 next day
- Moscow is UTC+3
- Difference: UTC+9 to UTC+3 = 6 hours behind
- 0130 - 6 = -04:30 → Add 24 → 2030
- Arrival in Moscow: 2030 (8:30 PM)

> ✔ Moscow: 2030
