Question

Пассажирский поезд за 8 часов прошел 480 километров а скорый поезд за 6 часов прошел 720 километров. Во сколько раз скорость пассажирского поезда меньше скорости скорого поезда.

Answer 1

1)480:8=60 км/ч скорость пассажир.п.; 2)720:6=120 км/ч скорость скорого поезда; 3)120:60=2 раза; Ответ: в 2 раза скорость пассажирского меньше, чем скорого

Answer 2

По условию:
- 1-ый поезд за 8 часов - прошел 480 километров.
- 2-ой поезд за 6 часов - прошел 720 километров.
- Во сколько раз, скорость 1-го поезда меньше, скорости 2-го поезда - ?
Решение:
1. $480:8=60$км/ч - скорость 1-го поезда. (Пассажирского).
2. $720:6=120$км/ч - скорость 2-го поезда. (Скорого).
3. $120:60= 2$км/ч - скорость 1-го поезда, меньше скорость 2-го поезда.
Ответ: В $2$км/ч, скорость 1-го пассажирского меньше, Скорости 2-го скорого поезда. 

Answer 3

Calculation of Speed

To find the ratio of the speeds of the passenger train and the express train, we need to calculate their respective speeds first.

Let's assume the speed of the passenger train is x km/h, and the speed of the express train is y km/h.

According to the given information: - The passenger train traveled 480 kilometers in 8 hours. - The express train traveled 720 kilometers in 6 hours.

Using the formula speed = distance / time, we can calculate the speeds of the two trains.

For the passenger train: - Speed of the passenger train = Distance traveled by the passenger train / Time taken by the passenger train - Speed of the passenger train = 480 km / 8 hours - Speed of the passenger train = 60 km/h

For the express train: - Speed of the express train = Distance traveled by the express train / Time taken by the express train - Speed of the express train = 720 km / 6 hours - Speed of the express train = 120 km/h

Calculation of Ratio

Now that we have the speeds of both trains, we can calculate the ratio of the passenger train's speed to the express train's speed.

The ratio can be calculated by dividing the speed of the passenger train by the speed of the express train:

Ratio = Speed of the passenger train / Speed of the express train

Substituting the values we calculated earlier:

Ratio = 60 km/h / 120 km/h

Simplifying the ratio:

Ratio = 1/2

Therefore, the speed of the passenger train is half the speed of the express train.
