Question

От двух городов одновременно отошли навстречу друг другу товарный и пассажирский поезда. Товарный поезд шёл со скоростью 56 км/ч, а пассажирский со скоростью 74 км/ч. Каково расстояние между городами, если поезда встретились через 4 ч? 2-я способами ​

Answer 1

Ответ:

1)56х4=224(км)

2)74х4=296(км)

3)224+296=520(км)

Ответ: Расстояние между городами 550 км

Пошаговое объяснение:

Answer 2

Ответ:520

1.

скорость сбл = 74+56=130 км/ч

1)130 * 4  = 520 км

2.

56 * 4 + 74 * 4 = 520 км

Answer 3

Calculation of the Distance between the Cities

To calculate the distance between the two cities, we need to consider the speeds of the freight and passenger trains and the time it takes for them to meet.

Given: - Speed of the freight train: 56 km/h - Speed of the passenger train: 74 km/h - Time taken for the trains to meet: 4 hours

To find the distance between the cities, we can use the formula:

Distance = Speed × Time

Let's calculate the distance using the given information.

1. Calculation using the speed of the freight train: - Speed of the freight train: 56 km/h - Time taken for the trains to meet: 4 hours - Distance covered by the freight train = Speed × Time = 56 km/h × 4 hours = 224 km

2. Calculation using the speed of the passenger train: - Speed of the passenger train: 74 km/h - Time taken for the trains to meet: 4 hours - Distance covered by the passenger train = Speed × Time = 74 km/h × 4 hours = 296 km

Therefore, the distance between the two cities is the sum of the distances covered by the freight and passenger trains:

Distance = Distance covered by the freight train + Distance covered by the passenger train = 224 km + 296 km = 520 km

So, the distance between the two cities is 520 km.
