Question

Из двух городов одновременно навстречу друг другу отправились посажирский поезд и товарный. Они встретелись через 6 ч. Каково расстояние между городами, если скорость пассажирского поезда 74 км/ч, а товарного 42 км/ч

Answer 1

1)74+42=116
2)116*6=696
Ответ:расстояние между городами равно 696 километров

Answer 2

1) 74+42=116( км/ч)- скорость сближения
2 ) 116* 6=696(км)
Ответ : расстояние между городами=696 километров.

Answer 3

Problem Analysis

We are given that a passenger train and a freight train start from two different cities simultaneously and meet after 6 hours. We need to find the distance between the cities given that the passenger train's speed is 74 km/h and the freight train's speed is 42 km/h.

Solution

Let's assume the distance between the two cities is D km.

We can use the formula: Distance = Speed × Time.

For the passenger train, the distance covered in 6 hours is 74 km/h × 6 h = 444 km.

For the freight train, the distance covered in 6 hours is 42 km/h × 6 h = 252 km.

Since the two trains meet after 6 hours, the sum of the distances covered by both trains should be equal to the total distance between the cities.

So, we have the equation: 444 km + 252 km = D km.

Simplifying the equation, we get: 696 km = D km.

Therefore, the distance between the cities is 696 km.

Answer

The distance between the two cities is 696 km.
