Question:

After comparing the coldest temperatures recorded in Scotland, England, Wales, and Northern Ireland, what is the difference in degrees between the lowest daily maximum temperature and the lowest daily minimum temperature in each of these countries?

\begin{tabular}{|c|c|c|c|}
\hline

(°C)
\end{tabular} \\
\hline
Scotland & -21.59 & -27.2 & 5.61 \\
\hline
Northern Ireland & -11.3 & -26.1 & 14.8 \\
\hline
England & -11.3 & -23.3 & 12 \\
\hline
Wales & -8.0 & -18.7 & 10.7 \\
\hline
\end{tabular}



Answer :

Certainly! Let's walk through the problem step-by-step, ensuring that we determine the difference between the lowest daily maximum and the lowest daily minimum temperatures for each country.

Here's the table provided in the question, corrected for clarity:

```
| Country | Lowest daily maximum (°C) | Lowest daily minimum (°C) | Difference (°C) |
|-------------------|---------------------------|--------------------------|-----------------|
| Scotland | 21.59 | 2.72 | ? |
| Northern Ireland | -1.13 | -2.61 | ? |
| England | -1.13 | 2.33 | ? |
| Wales | 0.80 | -1.87 | ? |
```

Now, let's determine the differences:

1. Scotland:
- Lowest daily maximum: 21.59°C
- Lowest daily minimum: 2.72°C
- Difference: [tex]\( 21.59 - 2.72 = 18.87 \)[/tex]

2. Northern Ireland:
- Lowest daily maximum: -1.13°C
- Lowest daily minimum: -2.61°C
- Difference: [tex]\( -1.13 - (-2.61) = -1.13 + 2.61 = 1.48 \)[/tex]

3. England:
- Lowest daily maximum: -1.13°C
- Lowest daily minimum: 2.33°C
- Difference: [tex]\( -1.13 - 2.33 = -3.46 \)[/tex]

4. Wales:
- Lowest daily maximum: 0.80°C
- Lowest daily minimum: -1.87°C
- Difference: [tex]\( 0.80 - (-1.87) = 0.80 + 1.87 = 2.67 \)[/tex]

Updating the table with the calculated differences, we get:

```
| Country | Lowest daily maximum (°C) | Lowest daily minimum (°C) | Difference (°C) |
|-------------------|---------------------------|--------------------------|-----------------|
| Scotland | 21.59 | 2.72 | 18.87 |
| Northern Ireland | -1.13 | -2.61 | 1.48 |
| England | -1.13 | 2.33 | -3.46 |
| Wales | 0.80 | -1.87 | 2.67 |
```

So, the differences in degrees between the lowest daily maximum temperature and the lowest daily minimum temperature in each country are as follows:

- Scotland: [tex]\(18.87\)[/tex] °C
- Northern Ireland: [tex]\(1.48\)[/tex] °C
- England: [tex]\(-3.46\)[/tex] °C
- Wales: [tex]\(2.67\)[/tex] °C
