Answer:
The number of ways five people can sit in a car with five seats depends on whether the seats are distinguishable or not.
1. **If the seats are indistinguishable:** In this case, the only consideration is how many people are in the car, as all seats are the same. There's only one way for five people to sit in the car.
2. **If the seats are distinguishable:** If the seats have unique positions, then the number of ways can be calculated using permutations. The first person has 5 choices for the seat, the second person has 4 remaining choices, the third person has 3, the fourth person has 2, and the last person has 1 choice. The total number of ways is the product of these choices: \(5 \times 4 \times 3 \times 2 \times 1 = 120\).
So, there are 120 different ways for five people to sit in a car with distinguishable seats.
