Question

Скорость товарного поезда 1,2км в минуту а скорость пассажирского поезда движущегося в том же направлении 1, 5 км минуту Найдите расстояние между ними в данный момент, если пассажирский поезд догонит товарный через 21 минуту?

Answer 1

1, 5 умножить на 21= 31,5 (км)-расстояние в данный момент.

Answer 2

1,5 * 21 = 31,5 км - И всё вроде бы:)

Answer 3

Calculating the Distance Between Trains

To find the distance between the two trains when the passenger train catches up to the freight train, we can use the formula:

Distance = Speed × Time

First, let's calculate the distance the freight train travels in 21 minutes at a speed of 1.2 km/min: ``` Distance of freight train = Speed of freight train × Time = 1.2 km/min × 21 min = 25.2 km ``` Now, let's calculate the distance the passenger train travels in 21 minutes at a speed of 1.5 km/min: ``` Distance of passenger train = Speed of passenger train × Time = 1.5 km/min × 21 min = 31.5 km ``` The distance between the two trains when the passenger train catches up to the freight train is the difference in the distances they have traveled. Therefore: ``` Distance between the trains = Distance of passenger train - Distance of freight train = 31.5 km - 25.2 km = 6.3 km ``` So, the distance between the two trains at the moment the passenger train catches up to the freight train is 6.3 kilometers.
