Question

Из двух городов, расстояние между которыми 1320 км, одновременно навстречу друг другу отправились пассажирские и товарные поезда. Встретились они через 12 часов. Найди скорость пассажирского поезда, если товарный двигался со скоростью 35 км/ч.

Answer 1

1) 1320:12 =110км/ч - скорость сближения
2) 110 - 35 = 75км/ч - скорость пассажирского поезда

Answer 2

Calculating the Speed of the Passenger Train

To find the speed of the passenger train, we can use the formula:

Total distance = (Speed of passenger train + Speed of freight train) * Time

Given: - Distance between the two cities = 1320 km - Speed of the freight train = 35 km/h - Time taken for the trains to meet = 12 hours

We can use the given information to calculate the speed of the passenger train.

Calculation

Using the formula mentioned above, we can calculate the speed of the passenger train as follows:

1320 = (Speed of passenger train + 35) * 12

Solving for the speed of the passenger train:

Speed of passenger train = (1320 / 12) - 35

Speed of passenger train = 110 - 35

Speed of passenger train = 75 km/h

So, the speed of the passenger train is 75 km/h.

This calculation is based on the provided information and the formula for calculating the speed of the passenger train.
