Question

1. the average temperature at the south pole is - 45°f. the average temperature on the equator is 92°f. how much warmer is the average temperature on the equator than at the south pole?

Explanation:

Step1: Identify the operation

We need to find the difference in temperature, so we use subtraction.

Step2: Subtract the South - Pole temperature from the Equator temperature

The temperature at the Equator is 92°F and at the South - Pole is - 45°F. The difference is $92-(-45)$.
Since subtracting a negative number is the same as adding a positive number, $92-(-45)=92 + 45$.
$92+45 = 137$.

Answer:

137°F
