Final answer:
It will take approximately 5.25 minutes for the temperature to reach 0 degrees Celsius.
Step-by-step explanation:
To calculate the time it takes for the temperature to reach 0 degrees Celsius, we can use the formula:
Time = (Final Temperature - Initial Temperature) / Rate of Temperature Change
Plugging in the given values:
Final Temperature = 0 degrees Celsius, Initial Temperature = -8.4 degrees Celsius, Rate of Temperature Change = 1.6 degrees Celsius per minute
Time = (0 - (-8.4)) / 1.6
Time = 8.4 / 1.6
Time = 5.25 minutes
Therefore, it will take approximately 5.25 minutes for the temperature to reach 0 degrees Celsius.
