Final answer:
The average rate of change of b from t=0 s to t=222 s can be determined using the equation or information about the relationship between b and t.
Step-by-step explanation:
The average rate of change of b from t=0 s to t=222 s can be determined by calculating the change in b divided by the change in time. In this case, we need the equation or information about the relationship between b and t to find the average rate of change. Please provide the necessary equation or information for a more accurate answer.
