Question

Скорость гоночного автомобиля 350 км/ч, а скорость скоростного поезда-250 км/ч.Кто проходит большее расстояние:гоночный автомобиль за 3 ч или скоростной поезд за 4 ч? •На сколько больше? Ребята помогите пожалуйста!!!УМОЛЯЮ!!! (4 класс).

Answer 1

Calculation of Distance Traveled

To determine which vehicle travels a greater distance, we need to calculate the distance traveled by each vehicle over their respective time periods.

Let's start with the racing car. The racing car has a speed of 350 km/h and travels for 3 hours. To calculate the distance traveled by the racing car, we can use the formula:

Distance = Speed × Time

Substituting the given values, we get:

Distance of racing car = 350 km/h × 3 hours

Next, let's calculate the distance traveled by the high-speed train. The high-speed train has a speed of 250 km/h and travels for 4 hours. Using the same formula as before, we have:

Distance of high-speed train = 250 km/h × 4 hours

Now, let's calculate the distances:

Distance of racing car = 350 km/h × 3 hours = 1050 km.

Distance of high-speed train = 250 km/h × 4 hours = 1000 km.

Therefore, the racing car travels a greater distance, covering 1050 km, while the high-speed train covers 1000 km.

Difference in Distance Traveled

To find the difference in distance traveled between the racing car and the high-speed train, we subtract the distance traveled by the high-speed train from the distance traveled by the racing car:

Difference in distance = Distance of racing car - Distance of high-speed train

Substituting the calculated values, we have:

Difference in distance = 1050 km - 1000 km = 50 km

Therefore, the racing car travels 50 km more than the high-speed train.

In summary: - The racing car travels a greater distance, covering 1050 km. - The high-speed train covers 1000 km. - The racing car travels 50 km more than the high-speed train.
