Question

Два поезда выехали одновременно из одного города в противоположных направлениях. Товарный поезд был в пути 2ч и двигался со скоростью 80км/ч. Пассажирский поезд за то же время проехал 200км. На каком расстоянии оказались друг от друга поезда за время движения? С какой скоростью ехал пассажирский поезд?

Answer 1

2*80+200 это на таком расстоянии
200/2 скорость пасажирного

Answer 2

Problem Analysis

We have two trains that start simultaneously from the same city, but in opposite directions. The freight train travels for 2 hours at a speed of 80 km/h, while the passenger train travels 200 km in the same time. We need to find the distance between the two trains and the speed of the passenger train.

Distance between the Trains

To find the distance between the two trains, we can add up the distances traveled by each train. Since the trains are moving in opposite directions, the total distance between them is equal to the sum of the distances traveled by each train.

The freight train travels for 2 hours at a speed of 80 km/h. Therefore, the distance traveled by the freight train is:

Distance of freight train = Speed of freight train × Time taken by freight train

Distance of freight train = 80 km/h × 2 hours

Using the formula, we can calculate the distance of the freight train.

Speed of the Passenger Train

To find the speed of the passenger train, we can divide the distance traveled by the passenger train by the time taken.

Speed of passenger train = Distance of passenger train ÷ Time taken by passenger train

Using the formula, we can calculate the speed of the passenger train.

Calculation

Let's calculate the distance between the two trains and the speed of the passenger train.

Distance of freight train = 80 km/h × 2 hours = 160 km Speed of passenger train = 200 km ÷ 2 hours = 100 km/h Therefore, the distance between the two trains is 160 km, and the speed of the passenger train is 100 km/h.
