Question

Два встречных поезда проходят мимо друг друга со скоростями 48 км/ч и 60 км/ч соответственно. Пассажир первого поезда заметил, что второй поезд прошёл мимо его окна за 10 с. Какова длина второго поезда?

Answer 1

Problem Analysis

We are given two trains passing each other. The first train has a speed of 48 km/h, and the second train has a speed of 60 km/h. The passenger in the first train noticed that the second train passed his window in 10 seconds. We need to find the length of the second train.

Solution

To find the length of the second train, we can use the formula:

Length = Speed × Time

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

Calculation

Given: - Speed of the first train = 48 km/h - Speed of the second train = 60 km/h - Time taken for the second train to pass the window of the first train = 10 seconds

Using the formula, we can calculate the length of the second train:

Length = Speed × Time

For the first train: Length of the first train = 48 km/h × 10 s

For the second train: Length of the second train = 60 km/h × 10 s

Answer

The length of the second train is 600 meters.

Explanation

The length of the second train is calculated by multiplying its speed by the time it takes to pass the window of the first train. In this case, the speed of the second train is 60 km/h, and the time taken to pass the window is 10 seconds. Multiplying these values gives us the length of the second train, which is 600 meters.
