Question

Два поезда в одно и тоже время вышли навстречу друг другу из железнодорожных вокзалов ташкента из нукуса.скорость первого поезда 75 километр в час.расстояние между городами 1255 километров.с какой скоростью двигался 2 поезд, если они встретились через 10 часов.

Answer 1

1255:10=125,5 км/час скорость сближения поездов
125,5-75=50,5 км/час скорость второго поезда
==================================

Answer 2

Сначала найдем сколько за 10 часов проехал первый поезд
75*10=750
теперь найдем путь второго поезда
1255-750=505
и в конце путь разделим на время
505:10=50.5 км/ч

Answer 3

Problem Analysis

We have two trains traveling towards each other from Tashkent and Nukus. The first train has a speed of 75 kilometers per hour, and the distance between the cities is 1255 kilometers. We need to find the speed of the second train if they meet after 10 hours.

Calculation

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

Let's calculate the time it takes for the trains to meet. Since they are traveling towards each other, their combined speed is the sum of their individual speeds.

The first train's speed is given as 75 kilometers per hour. Let's denote the speed of the second train as 'x' kilometers per hour.

The total distance between the cities is 1255 kilometers.

The time it takes for the trains to meet is 10 hours.

Using the formula Speed = Distance / Time, we can set up the equation:

75 + x = 1255 / 10

Simplifying the equation:

75 + x = 125.5

Subtracting 75 from both sides:

x = 125.5 - 75

x = 50.5

Answer

The second train was traveling at a speed of 50.5 kilometers per hour.

Explanation

The first train was traveling at a speed of 75 kilometers per hour, and the second train was traveling at a speed of 50.5 kilometers per hour. They met after 10 hours of travel time.
