Question

Из двух городов одновременно на встречу друг другу отправились через 12ч.Определите расстояние между городами,если известно,что скорость пассажирского поезда 75 км/ч ,а товарного - 35км/ч

Answer 1

1)35+75=110(км/ч)-Vсближения
2)110*12=132(км)
Ответ:132км.

Answer 2

Calculating the Distance Between Two Cities

To calculate the distance between two cities, we can use the formula: distance = speed * time

Given: - Speed of the passenger train = 75 km/h - Speed of the freight train = 35 km/h - Time = 12 hours

We can calculate the distance using the formula for each train and then find the total distance.

For the passenger train: distance_passenger = speed_passenger * time

For the freight train: distance_freight = speed_freight * time

Let's calculate the distances for each train and then find the total distance.

Calculations

For the passenger train: distance_passenger = 75 km/h * 12 h = 900 km

For the freight train: distance_freight = 35 km/h * 12 h = 420 km

Total Distance

The total distance between the two cities is the sum of the distances covered by the passenger and freight trains: total_distance = distance_passenger + distance_freight = 900 km + 420 km = 1320 km

Therefore, the distance between the two cities is 1320 kilometers.
