Answer:
[tex]-63.5\text{ F}[/tex].
Step-by-step explanation:
We have been given that the temperature on mars ranges widely from -207 f to 80 f. We are asked to find the average of the temperature extremes on mars.
To find the average of the temperature extremes on mars, we will divide the sum of both temperatures by 2 as:
[tex]\text{Average of the temperature extremes on mars}=\frac{-207\text{ F}+80\text{ F}}{2}[/tex]
[tex]\text{Average of the temperature extremes on mars}=\frac{-127\text{ F}}{2}[/tex]
[tex]\text{Average of the temperature extremes on mars}=-63.5\text{ F}[/tex]
Therefore, the average of the temperature extremes on mars is [tex]-63.5\text{ F}[/tex].
