Question

Из двух городов отправились одновременно навстречу друг другу два поезда со скоростями 48км ч и 54км ч .Найдите расстояние между городами если поезда встретились через 4 ч после начала движения

Answer 1

54+48=102 км/ч скорость сближения поездов.

102*4=408 км расстояние между городами.

Ответ: 408 км.

Answer 2

U1=48 км/ч
U2=54/ч
t=4 часа
1) 48×4=192 (км)-первый поезд
2)54×4=216 (км)-второй поезд
3)192+216=408 (км)-всего
Ответ: S=408 км

Answer 3

Calculation of Distance between Cities

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

Distance = Speed x Time

Given that the two trains are traveling towards each other, we can add their speeds to find the relative speed at which they are approaching each other.

Let's calculate the distance between the cities using the given information:

- Train 1 speed: 48 km/h - Train 2 speed: 54 km/h - Time taken to meet: 4 hours

The relative speed at which the trains are approaching each other is the sum of their speeds:

Relative Speed = Speed of Train 1 + Speed of Train 2

Relative Speed = 48 km/h + 54 km/h = 102 km/h

Now, we can use the formula to calculate the distance:

Distance = Relative Speed x Time

Distance = 102 km/h x 4 hours = 408 km

Therefore, the distance between the two cities is 408 kilometers.
