Answer:
There is a difference of 133ºF between the average temperatures of the South Pole and the Equator.
Explanation:
Given that the average temperature of the South Pole is -47ºF, while the average temperature of the Ecuator is 86ºF, to determine the difference in temperature between both regions of the planet, the following mathematical operation must be performed: 
86 - (-47) = X 
86 + 47 = X 
133 = X 
Therefore, there is a difference of 133ºF between the average temperatures of the South Pole and the Equator.
