To find the unit rate of passengers per car, you divide the total number of passengers by the total number of cars.
Given:
- 48 passengers
- 16 cars
Unit rate (passengers per car) = Total passengers / Total cars
Calculating:
\[ \text{Unit rate} = \frac{48 \text{ passengers}}{16 \text{ cars}} = 3 \text{ passengers per car} \]
So, the unit rate is 3 passengers per car.
