1 answer

To find the unit rate of passengers per car, you can divide the total number of passengers by the total number of cars:

\[ \text{Unit rate} = \frac{\text{Total passengers}}{\text{Total cars}} = \frac{81 \text{ passengers}}{27 \text{ cars}} = 3 \text{ passengers per car} \]

So, the unit rate is 3 passengers per car.
