To determine how many degrees cooler it was in Bristol at 06:00 compared to Mallorca at 18:00, we use the given temperatures from the tables.
Firstly, let's identify the temperatures at the specified times:
- In Bristol at 06:00, the temperature was [tex]\(-1^{\circ}\)[/tex].
- In Mallorca at 18:00, the temperature was [tex]\(15^{\circ}\)[/tex].
To find the difference in temperature between these two times and locations, we subtract the Bristol temperature from the Mallorca temperature:
[tex]\[
15^{\circ} - (-1^{\circ}) = 15^{\circ} + 1^{\circ} = 16^{\circ}
\][/tex]
Therefore, the temperature in Bristol at 06:00 was 16 degrees cooler than in Mallorca at 18:00.
The correct answer is:
C [tex]\(16^{\circ}\)[/tex]
