Answer:
the rate of temperature change from time 0 to time 4 is - 2 °C/time unit.
Step-by-step explanation:
the average rate of change = (final temp - initial temp)/time
average rate of change = (28-36)/4
= - 2 °C/time unit
Therefore, the rate of temperature change from time 0 to time 4 is - 2 °C/time unit.
