Question

Два электровоза одновременно отошлиот одной станции в противоположном направлении. скорость 1 130км/ч. 2 -100 км/чкакое расстояние будет между нимичерез 4 часа

Answer 1

1) 130 + 100 = 230 (км/ч) - скорость расхождения
2) 230 * 4 = 920 (км) пройдут за 4 часа оба электровоза
Ответ: 920 км- расстояние между электровозами через 4 часа.

Answer 2

Скорость первого электровоза - 120 км/ч
Скорость второго - 100 км/ч

1) 130 + 100=230 (км) - скорость удаления
2) 230*4=920 (км)

Ответ: через часа расстояние между паровозами будет равно 920 км.

Удачи!!!

Answer 3

Calculation of Distance between Two Trains

To calculate the distance between two trains that depart from the same station in opposite directions, we can use the formula:

Distance = (Speed of Train 1 + Speed of Train 2) * Time

Given the following information: - Speed of Train 1: 130 km/h - Speed of Train 2: -100 km/h (negative sign indicates opposite direction) - Time: 4 hours

We can substitute these values into the formula to find the distance between the two trains after 4 hours.

Distance = (130 km/h + (-100 km/h)) * 4 hours

To simplify the calculation, we can remove the negative sign from the speed of Train 2:

Distance = (130 km/h + 100 km/h) * 4 hours

Now we can calculate the distance:

Distance = 230 km/h * 4 hours

Distance = 920 km

Therefore, after 4 hours, the distance between the two trains will be 920 kilometers.

Please note that the negative sign in the speed of Train 2 indicates that it is moving in the opposite direction.
