Question

Из двух городов в 8 часов навстречу друг другу выехали два пассажирских поезда и встретились в 12 часов. Скорость одного поезда 82 км в час. С какой скоростью ехал другой поезд, если расстояние между городами 720 км? ЕСЛИ МОДНО ПОЖАЛУЙСТА НАПИШИТЕ УСЛОВИЕ ТАБЛИЦОЙ!!!!!!!!!

Answer 1

12-8=4час пути
720-4×82=720-328=392км
392÷4=98км/час

Answer 2

Problem Analysis

Two passenger trains started traveling towards each other from two different cities at 8:00 am and met at 12:00 pm. The speed of one train is given as 82 km/h, and the distance between the cities is 720 km. We need to find the speed of the other train.

Solution

To solve this problem, we can use the formula: Speed = Distance / Time.

Let's calculate the time it took for the trains to meet. The first train started at 8:00 am and met the second train at 12:00 pm, which means they traveled for 4 hours.

Now, let's calculate the speed of the second train using the formula mentioned above.

Calculation

- Distance between the cities = 720 km - Time taken to meet = 4 hours - Speed of the first train = 82 km/h

Using the formula Speed = Distance / Time, we can calculate the speed of the second train as follows:

Speed of the second train = Distance / Time = 720 km / 4 hours = 180 km/h.

Therefore, the speed of the second train is 180 km/h.

Table Representation

Here is the table representation of the problem:

| Train | Speed (km/h) | Time (hours) | Distance (km) | |-------|--------------|--------------|---------------| | Train 1 | 82 | 4 | 328 | | Train 2 | ? | 4 | 392 |

Since the two trains meet in the middle, the distance traveled by each train is half the total distance between the cities.
