Answer 1

Для 1 схемы
54км\час + 36км\час = 90км - растояние между обьектами за 1 час езды90км * 3часа = 270км - растояние удаления обоих обьектов друг от друга за 3 часа
Для схемы 2
Если догоняет объект1 объект2 
20км\час - 15км\час = 5км будет увеличиваться растояние между обьектами
5км * 3часа= 15км увеличиться растояние между обьектами за 3 часа

Answer 2

Calculation of Speed and Distance Changes

To determine the speed of convergence or divergence and the change in distance between objects after 3 hours, we need to analyze each scheme separately. Let's break down the given schemes and calculate the required values.

1) 4 km/h → ? → 12 km/h

In this scheme, the initial speed is 4 km/h, and the final speed is 12 km/h. To calculate the speed of convergence or divergence, we need to determine the direction of the objects' movement. Unfortunately, the given scheme does not provide this information. Without knowing the direction, we cannot determine whether the objects are moving towards each other or away from each other.

Similarly, without knowing the direction, we cannot accurately calculate the change in distance between the objects after 3 hours. We need to know whether the objects are moving towards each other or away from each other to calculate the change in distance.

2) ? → ? → S will increase by 6 km/h after 3 hours, S will increase by 19 km/h

In this scheme, the change in speed is given, but the initial and final speeds are not provided. Without this information, we cannot determine the speed of convergence or divergence.

However, we are given that the distance (S) between the objects will increase by 6 km/h after 3 hours and will increase by 19 km/h. This suggests that the objects are moving away from each other.

Again, without knowing the initial distance between the objects, we cannot accurately calculate the change in distance after 3 hours.

3) 54 km/h → 36 km/h → ? → ?

In this scheme, the initial speed is 54 km/h, and the final speed is 36 km/h. Unfortunately, the intermediate speeds are not provided, so we cannot determine the speed of convergence or divergence.

Without knowing the direction, we cannot accurately calculate the change in distance between the objects after 3 hours.

4) 20 km/h → 15 km/h → ? → ?

In this scheme, the initial speed is 20 km/h, and the final speed is 15 km/h. Similar to the previous schemes, the intermediate speeds are not provided, so we cannot determine the speed of convergence or divergence.

Without knowing the direction, we cannot accurately calculate the change in distance between the objects after 3 hours.

Conclusion

Based on the given schemes, we are unable to determine the speed of convergence or divergence for any of the scenarios. Additionally, without knowing the initial distances between the objects, we cannot accurately calculate the change in distance after 3 hours.

Please provide additional information or clarify the given schemes if you would like a more accurate analysis.
