Question

Пассажирский поезд за 8 ч прошёл 384 км, а скорый поезд за 7 ч -420 км. Скорость какого поезда больше и на сколько?

Answer 1

1)384:8=48(км/ч)-скорость пассажирского поезда.
2)420:7=60(км/ч)-скорость скорого поезда.
3)60-48=12(км/ч)-разность.
Ответ:Скорый поезд быстрее на 12 км/ч.

Answer 2

384/8=48км/ч - скорость пассажар.поезда
420/7=60 км/ч - скорость скорого поезда
60-48=12 км/ч - на столько скорость скорого больше пассажирского 

Answer 3

Calculation of Train Speeds

To determine the speed of each train, we can use the formula: speed = distance / time.

Let's calculate the speed of the passenger train first. The passenger train traveled a distance of 384 km in 8 hours. Using the formula, we can calculate its speed as follows:

Passenger train speed = 384 km / 8 hours = 48 km/h.

Now, let's calculate the speed of the express train. The express train traveled a distance of 420 km in 7 hours. Using the formula, we can calculate its speed as follows:

Express train speed = 420 km / 7 hours = 60 km/h.

Comparison of Train Speeds

The speed of the express train is 60 km/h, while the speed of the passenger train is 48 km/h. Therefore, the express train is faster than the passenger train by 12 km/h.
