Answer:
18°c
Explanation:
Midnight temperature in Johannesburg = -5°c
Midnight temperature in Durban = 13°c
Now we want to find how much higher the temperature in Durban is above the temperature in Johannesburg. We do this by finding the difference between the temperature in Durban and the temperature in Johannesburg .
So,
Difference between the temperature in Durban and the temperature in Johannesburg = 13 - (-5) = 18°c
