Question

Из пункта А вышел поезд спустя 2 часа с этого же города в противоположном направлении вышел другой поезд через 3 часа после выхода второго поезда расстояние между поездами было 402 км Найдите скорость второго поезда если она на 6 км в час больше скорости первого поезда

Answer 1

402/3=134км в час
134+6=140

Answer 2

Problem Analysis

We are given that a train leaves point A after 2 hours, and another train leaves the same point in the opposite direction after 3 hours. The distance between the trains is 402 km, and the speed of the second train is 6 km/h faster than the speed of the first train. We need to find the speed of the second train.

Solution

Let's assume the speed of the first train is x km/h. Since the second train is 6 km/h faster, its speed will be x + 6 km/h.

To find the solution, we can use the formula: speed = distance / time.

Let's calculate the time it takes for the first train to cover the distance between the trains. Since the first train leaves 2 hours before the second train, the time it takes for the first train to cover the distance is 3 - 2 = 1 hour.

Now, let's calculate the time it takes for the second train to cover the distance. Since the second train leaves 3 hours after the first train, the time it takes for the second train to cover the distance is 3 hours.

Using the formula speed = distance / time, we can calculate the speed of the second train as follows:

Speed of the second train = Distance / Time = 402 km / 3 hours = 134 km/h.

Therefore, the speed of the second train is 134 km/h.

Answer

The speed of the second train is 134 km/h.
