Given Table:



| From | To | Distance (miles) | Distance to nearest 100 miles |
|------------------|--------------|------------------|-------------------------------|
| Washington DC | Los Angeles | 2295 | 2300 |
| Los Angeles | Tokyo | 5472 | ? |
| Tokyo | Bombay | 4189 | ? |
| Bombay | Athens | 3214 | ? |
| Athens | Paris | 1302 | ? |
| Paris | London | 213 | ? |
| London | Washington DC| 3665 | ? |

1) Fill in the distance to the nearest 100 miles column.



We round each distance to the nearest 100 miles:

- 2295 → 2300 (already given)
- 5472 → 5500 (since 5472 is closer to 5500 than 5400)
- 4189 → 4200 (closer to 4200 than 4100)
- 3214 → 3200 (closer to 3200 than 3300)
- 1302 → 1300 (closer to 1300 than 1400)
- 213 → 200 (closer to 200 than 300)
- 3665 → 3700 (closer to 3700 than 3600)

Now fill the table:

| From | To | Distance (miles) | Distance to nearest 100 miles |
|------------------|--------------|------------------|-------------------------------|
| Washington DC | Los Angeles | 2295 | 2300 |
| Los Angeles | Tokyo | 5472 | 5500 |
| Tokyo | Bombay | 4189 | 4200 |
| Bombay | Athens | 3214 | 3200 |
| Athens | Paris | 1302 | 1300 |
| Paris | London | 213 | 200 |
| London | Washington DC| 3665 | 3700 |

2) Put the distances in order from shortest to longest.



List the original distances and sort them:

- 213 (Paris → London)
- 1302 (Athens → Paris)
- 2295 (Washington DC → Los Angeles)
- 3214 (Bombay → Athens)
- 3665 (London → Washington DC)
- 4189 (Tokyo → Bombay)
- 5472 (Los Angeles → Tokyo)

So, ordered from shortest to longest:

213, 1302, 2295, 3214, 3665, 4189, 5472

Fill in:

```
______ ______ ______ ______ ______ ______ ______
shortest longest
```

Answer:
213, 1302, 2295, 3214, 3665, 4189, 5472

3) How much further is the trip from Bombay to Athens than the trip from Washington DC to Los Angeles?



- Bombay → Athens = 3214 miles
- Washington DC → Los Angeles = 2295 miles

Difference = 3214 - 2295 = 919 miles

Answer: 919 miles

---

4) What is the total distance from Los Angeles to Tokyo to Bombay to Athens?



Add the distances:

- Los Angeles → Tokyo = 5472
- Tokyo → Bombay = 4189
- Bombay → Athens = 3214

Total = 5472 + 4189 + 3214

Calculate:

5472 + 4189 = 9661
9661 + 3214 = 12,875 miles

Answer: 12,875 miles

5) Tyger says 'The distance from Washington DC to Los Angeles is more than 10 times the distance from Paris to London.' Is he right?



- Washington DC → Los Angeles = 2295 miles
- Paris → London = 213 miles

10 × 213 = 2130

Is 2295 > 2130? Yes!

So, yes, Tyger is right.

Answer: Yes

---

6) When arriving at Bombay, Tyger says 'So far we have travelled over 12,000 miles.' Is he right?



We need to sum all distances up to Bombay:

Path:
1. Washington DC → Los Angeles = 2295
2. Los Angeles → Tokyo = 5472
3. Tokyo → Bombay = 4189

Total = 2295 + 5472 + 4189

Calculate:

2295 + 5472 = 7767
7767 + 4189 = 11,956 miles

Is 11,956 > 12,000? No — it's less than 12,000.

So, no, Tyger is not right.

Answer: No

2) 213, 1302, 2295, 3214, 3665, 4189, 5472
3) 919 miles
4) 12,875 miles
