Question

Зробіть пж задачу: З однієї станції в одному напрямі вирушили два поїзди. Один рухався зі швидкістю 64,7км/год, а другий-56,9км/год. Яка відстань буде між ними через 1,4 год після початку руху? Допоможіть просто я не вмію розв'язувати задачі

Answer 1

1) 64,7 - 56,9 = 7,8 (км/ч) - скорость опережения одного поезда (или отставания другого);

2) 7,8 · 1,4 = 10,92 (км) - расстояние между поездами через 1,4 часа.

Выражение: (64,7 - 56,9) · 1,4 = 10,92.

Ответ: 10 км 920 м.

Answer 2

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's calculate the distance between the two trains after 1.4 hours.

Train 1 is moving at a speed of 64.7 km/h, and Train 2 is moving at a speed of 56.9 km/h.

Using the formula, we can calculate the distance traveled by each train after 1.4 hours:

Distance traveled by Train 1 = 64.7 km/h × 1.4 hours

Distance traveled by Train 2 = 56.9 km/h × 1.4 hours

Now, let's calculate the distances:

Distance traveled by Train 1 = 90.58 km

Distance traveled by Train 2 = 79.66 km

To find the distance between the two trains, we subtract the distance traveled by Train 2 from the distance traveled by Train 1:

Distance between the two trains = Distance traveled by Train 1 - Distance traveled by Train 2

Distance between the two trains = 90.58 km - 79.66 km

Distance between the two trains = 10.92 km

Therefore, the distance between the two trains after 1.4 hours will be approximately 10.92 km.
