Answer:
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
Step-by-step explanation:
We know that the temperature of the freezer is never greater than -2°C. Yesterday the temperature was -10°C but it increased at a steady rate of 1.5°C per hour. We calculate how long in hours and minutes did the temperature increase inside the freezer.
We conclude that the difference in temperature is 8°C.
We get:
[tex]t=\frac{8}{1.5}\\\\t=5.333[/tex]
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
