Question

Скорость товарного поезда 76 км в час. это в три раза меньше чем скорость экспресса.на сколько км Большое проедет экспресс за 4 часа чем товарный поезд за то же время?

Answer 1

1)76 км\ ч *3=228 км\ ч -скорость экспресса;
2) 228 км\ ч * 4=912км

Answer 2

76*3=228 (км/час) - скорость экспресса
76*4=304 (км) - сколько проедет товарный поезд за 4 часа
228*4=912 (км) - сколько проедет экспрессо
912-304=608 (км) - расстояние между ними за 4 часа

Answer 3

Calculation of Distance Traveled

To calculate the distance traveled by the express train in 4 hours compared to the freight train, we need to know the speed of the express train. The question states that the speed of the freight train is 76 km/h, which is three times slower than the speed of the express train.

Let's assume the speed of the express train is x km/h. According to the given information, the speed of the freight train is 76 km/h. Therefore, the speed of the express train can be calculated as:

x = 3 * 76

Now, we can calculate the distance traveled by each train in 4 hours.

The distance traveled by the freight train in 4 hours is:

Distance of freight train = Speed of freight train * Time

Distance of freight train = 76 km/h * 4 hours

The distance traveled by the express train in 4 hours is:

Distance of express train = Speed of express train * Time

Distance of express train = (3 * 76) km/h * 4 hours

Let's calculate the distances:

Distance of freight train = 76 km/h * 4 hours = 304 km

Distance of express train = (3 * 76) km/h * 4 hours = 912 km

Therefore, the express train will travel 912 km in 4 hours, which is 608 km more than the freight train.

Please note that the above calculation assumes a constant speed for both trains throughout the entire 4-hour period. In reality, train speeds may vary due to factors such as acceleration, deceleration, and stops.
