Answer:
The difference in these temperature extremes in Africa is: 147 °F
Explanation:
As per the statement:
The highest temperature ever recorded in Africa was 136°F in Libya.
⇒Highest temperature = 136 °F
It is also given that:
The lowest temperature ever recorded in Africa was –11°F in Morocco.
⇒Lowest temperature = -11 °F
We have to find the difference in these temperature extremes.

Substitute the value we have;
= 136-(-11) = 136+11=147°F
Therefore, the difference in these temperature extremes in Africa is: 147 °F
