The formula to calculate the alcohol burn off rate (ABOR) is:
\[ ABOR = \frac{BAC}{T} \]
Where:
Let's say the total change in BAC (CBAC) is 0.08 and the total time (T) is 4 hours. Using the formula:
\[ ABOR = \frac{0.08}{4} \]
We get:
\[ ABOR = 0.02 \, \text{BAC/hour} \]
So, the alcohol burn off rate is 0.02 BAC/hour.
