Answer 1

QUESTION 1

When the plane reaches an altitude of 360,000 feet, the temperature outside the plane is 65 degrees below zero Fahrenheit.

This means that the temperature will be:

$0-65=-65$

The temperature is -65°F.

QUESTION 2

If the temperature gets warmer by 10 degrees, this means that the new temperature will be the sum of the original temperature and 10 degrees:

$\Rightarrow-65+10=-55$

The temperature is -55°F.
