Question

решите плииизз!)))пассажирский и товарный поезд выехали одновременно в противоположных направлениях из двух городов, расстояние между которыми 70км. скорость пассажирского 80 км/ч. а скорость товарного составляет 11/16 скорости пассажирского. на каком расстояние друг от друга будет поезд черз 3 часа?

Answer 1

скорость товарного равна 80*11/16=55 км/ч

пассажирский проедет 3*80=240 км

товарный проедет 3*55=165 км

всего расстояние между ними будет 240+165+70=475 км

Answer 2

1) (80/16)*11=55(км/ч) скорость товарного,

2)(80+55)*3+70=475(КМ)БУДЕТ МЕЖДУ НИМИ ЧЕРЕЗ 3 ЧАСА 

Answer 3

Problem Analysis

We have a passenger train and a freight train that start simultaneously from two cities in opposite directions. The distance between the cities is 70 km. The passenger train travels at a speed of 80 km/h, while the freight train travels at 11/16 of the passenger train's speed. We need to determine the distance between the trains after 3 hours.

Calculation

To solve this problem, we can use the formula: distance = speed * time.

Let's calculate the distance traveled by the passenger train in 3 hours: distance_passenger = speed_passenger * time = 80 km/h * 3 h = 240 km.

Now, let's calculate the distance traveled by the freight train in 3 hours: speed_freight = (11/16) * speed_passenger = (11/16) * 80 km/h = 55 km/h. distance_freight = speed_freight * time = 55 km/h * 3 h = 165 km.

Since the trains are moving in opposite directions, the total distance between them after 3 hours is the sum of the distances traveled by each train: total_distance = distance_passenger + distance_freight = 240 km + 165 km = 405 km.

Answer

After 3 hours, the passenger train and the freight train will be approximately 405 km apart from each other.
