Problem Analysis

The problem states that two friends agreed to sit in the fourth car of an electric train. However, one boy sat in the fourth car from the beginning, while the other boy sat in the fourth car from the end of the train. The question is whether both boys are in the same car if there are 8 cars in total.

Solution

To solve this problem, we need to determine if the two boys are in the same car. Let's analyze the situation step by step:

1. The first boy sits in the fourth car from the beginning. This means that there are three cars in front of him. 2. The second boy sits in the fourth car from the end. This means that there are three cars behind him. 3. Since there are 8 cars in total, we can calculate the number of cars between the two boys by subtracting the cars in front of the first boy and the cars behind the second boy from the total number of cars: - Cars between the two boys = Total cars - Cars in front of the first boy - Cars behind the second boy - Cars between the two boys = 8 - 3 - 3 = 2

Conclusion

Based on the calculations, there are two cars between the two boys. Therefore, they are not in the same car.
