Problem Analysis

Two cars start simultaneously from point A and travel in opposite directions. The first car travels at a speed of 60 kilometers per hour, while the second car travels at a speed of 70 kilometers per hour. The distance between them is 90 kilometers. We need to find the total distance traveled by the cars until they reach their respective destinations.

Solution

To find the total distance traveled by the cars, we need to determine the time it takes for each car to reach its destination. We can then multiply the time by the respective speeds to find the distances traveled.

Let's calculate the time it takes for each car to reach its destination:

- For the first car: - Speed = 60 kilometers per hour - Distance = 90 kilometers - Time = Distance / Speed = 90 / 60 = 1.5 hours

- For the second car: - Speed = 70 kilometers per hour - Distance = 90 kilometers - Time = Distance / Speed = 90 / 70 ≈ 1.286 hours

Now, let's calculate the distances traveled by each car:

- For the first car: - Distance = Speed * Time = 60 * 1.5 = 90 kilometers

- For the second car: - Distance = Speed * Time = 70 * 1.286 ≈ 90 kilometers

Therefore, the total distance traveled by both cars until they reach their respective destinations is 90 kilometers.

Answer

The total distance traveled by the two cars until they reach their respective destinations is 90 kilometers.
