<span>Average of any physical quantity is defined over an interval of time. Therefore, the average temperature for this case should be calculated as follows:
Average temperature = (final temp. - initial temp.) / total time
</span>Average temperature = (-24 - 0) / 4
Average temperature = -6°C
Hope this answers the question. Have a nice day.
