Question

Реши задачу Из двух городов расстояние между которыми 484 км вышли Одновременно навстречу друг другу два поезда Скорость одного поезда 4 км ч Определите скорость другого поезда Если Поезда встретились через 4 часа​

Answer 1

Ответ:

117 км/ч

Пошаговое объяснение:

1) 4 · 4 = 16 (км) - Расстояние 1 поезда за 4 часа

2) 484 - 16 = 468 (км) - Проехал 2 поезд за 4 часа

3) 468 : 4 = 117 (км/ч) - Скорость 2 поезда

Answer 2

ОтветВідповідь:117 км/ч

Answer 3

Problem Analysis

We are given that the distance between two cities is 484 km. Two trains start simultaneously from these cities and move towards each other. The speed of one train is given as 4 km/h. We need to determine the speed of the other train if the trains meet after 4 hours.

Solution

Let's assume the speed of the other train is x km/h.

Since the trains are moving towards each other, their combined speed is the sum of their individual speeds. Therefore, the combined speed of the two trains is 4 km/h + x km/h.

We know that distance = speed × time. In this case, the distance between the two cities is 484 km and the time taken for the trains to meet is 4 hours.

Using the formula distance = speed × time, we can write the equation:

484 km = (4 km/h + x km/h) × 4 hours

Now, let's solve this equation to find the value of x.

484 km = (4 km/h + x km/h) × 4 hours

484 km = (4 + x) × 4

484 km = 16 + 4x

4x = 484 km - 16

4x = 468 km

x = 468 km / 4

x = 117 km/h

Therefore, the speed of the other train is 117 km/h.

Answer

The speed of the other train is 117 km/h.
