Question

Космічна станція відправила поштовий контейнер на другу станцію. Першу чверть шляху контейнер рухався зі швидкістю 350 м/с, а решту шляху – зі швидкістю 200 м/с. Обчисліть середню швидкість руху поштового контейнеру.

Answer 2

To calculate the average speed of the postal container, we need to consider the distances traveled at different speeds. The container traveled the first quarter of the distance at a speed of 350 m/s and the remaining distance at a speed of 200 m/s.

Let's assume the total distance traveled by the postal container is D.

The first quarter of the distance is D/4, and the remaining distance is 3D/4.

The time taken to cover the first quarter of the distance can be calculated using the formula: time = distance / speed. Therefore, the time taken to cover the first quarter of the distance is (D/4) / 350.

Similarly, the time taken to cover the remaining distance can be calculated as (3D/4) / 200.

To find the average speed, we can use the formula: average speed = total distance / total time.

Let's calculate the average speed step by step:

1. Calculate the time taken to cover the first quarter of the distance: - Time1 = (D/4) / 350

2. Calculate the time taken to cover the remaining distance: - Time2 = (3D/4) / 200

3. Calculate the total time taken: - Total time = Time1 + Time2

4. Calculate the average speed: - Average speed = D / Total time

Now, let's calculate the average speed of the postal container:

Calculation:

1. Time taken to cover the first quarter of the distance: - Time1 = (D/4) / 350

2. Time taken to cover the remaining distance: - Time2 = (3D/4) / 200

3. Total time taken: - Total time = Time1 + Time2

4. Average speed: - Average speed = D / Total time

Please provide the value of the total distance (D) so that we can calculate the average speed of the postal container.
