Question

Два поезда вышли одновременно навстречу друг другу из двух городов ,растояние между которыми 650км ,и встретились через пять часов.Чему равна скорость второго поезда ,если скорость первого равна 62км\ч?

Answer 1

62*5= 310 км прошел первый поезд
650-310= 340 км прошел второй поезд
340:5= 68 км/ч сеорость второго поезда

Answer 2

62 * 5 =310 км проехал первый

650 - 310 = 340 проехал второй

340 : 5 =68 км/ч скорость второго

ОТВЕТ 68 км/ч

Answer 3

Problem Analysis

We have two trains that start simultaneously from two different cities and meet each other after five hours. The distance between the two cities is 650 km. We need to find the speed of the second train, given that the speed of the first train is 62 km/h.

Solution

To find the speed of the second train, we can use the formula: Speed = Distance / Time.

Let's calculate the speed of the second train using this formula.

Calculation

The distance between the two cities is 650 km, and the time taken to meet is 5 hours.

For the first train: - Speed of the first train = 62 km/h - Distance covered by the first train = Speed * Time = 62 km/h * 5 h = 310 km

Since the two trains meet each other, the sum of the distances covered by both trains should be equal to the total distance between the two cities.

For the second train: - Distance covered by the second train = Total distance - Distance covered by the first train = 650 km - 310 km = 340 km - Time taken by the second train = Time taken by the first train = 5 hours

Now, we can calculate the speed of the second train: - Speed of the second train = Distance covered by the second train / Time taken by the second train = 340 km / 5 h = 68 km/h

Answer

The speed of the second train is 68 km/h.
