Problem Analysis

Two cars are traveling towards each other from points A and B, which are 250 km apart. The speeds of the cars are 60 km/h and 40 km/h, respectively. We need to determine how long it will take for the cars to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed. We will calculate the time it takes for each car to reach the meeting point, and then take the maximum of these two times as the answer.

Let's calculate the time it takes for each car to reach the meeting point:

- Car A: The distance between point A and the meeting point is 250 km. The speed of car A is 60 km/h. Therefore, the time it takes for car A to reach the meeting point is 250 km / 60 km/h = 4.17 hours.

- Car B: The distance between point B and the meeting point is also 250 km. The speed of car B is 40 km/h. Therefore, the time it takes for car B to reach the meeting point is 250 km / 40 km/h = 6.25 hours.

Since car B takes longer to reach the meeting point, we can conclude that the cars will meet after approximately 6.25 hours.

Answer

The cars will meet after approximately 6.25 hours.
