Answer:
[tex]213.8\°F[/tex]
Step-by-step explanation:
we know that
To find out the difference between these two temperatures subtract the temperature measured at Prospect creek Alaska from the temperature measured at death Valley California
so
[tex]134\°F-(-79.8\°F)[/tex]
Remember that
[tex](-1)(-1)=+1[/tex]
so
[tex]134\°F+79.8\°F=213.8\°F[/tex]
