Problem Analysis

We are given that a truck and a car start their journey simultaneously from points A and B, respectively. The truck meets the car after 2 hours and arrives at point B after 3 more hours. We need to determine how much time the car spent traveling from B to A.

Solution

Let's break down the information given:

- The truck meets the car after 2 hours. - The truck arrives at point B after 3 more hours.

To find the time the car spent traveling from B to A, we need to subtract the time it took for the truck to reach point B from the total time it took for the truck and the car to meet.

Let's calculate the total time it took for the truck and the car to meet:

- The truck met the car after 2 hours. - The truck arrived at point B after 3 more hours. - Therefore, the total time it took for the truck and the car to meet is 2 + 3 = 5 hours.

Now, let's calculate the time it took for the truck to reach point B:

- The truck arrived at point B after 3 hours. - Therefore, the time it took for the truck to reach point B is 3 hours.

To find the time the car spent traveling from B to A, we subtract the time it took for the truck to reach point B from the total time it took for the truck and the car to meet:

5 hours - 3 hours = 2 hours.

Therefore, the car spent 2 hours traveling from B to A.

Answer

The car spent 2 hours traveling from B to A.
