Question

Два поезда одновремено вышли навстречу друг другу со станцыи расстояние между ними было 385км и встретились за 5 ч Скорость одного поезда 40км/ч. Найдите скорость 2 поезда

Answer 1

1) 40×5=200(км) - прошел первый
2) 385-200=185 (км) - прошел второй
3) 185:5=37 (км/ч) - скорость второго
Ответ: 37 км/ч.

Answer 2

1)5*40=200(км)-пррехал один поезд
2)385-200=185(км)-проехал второй поезд
3)185:5=37(км/ч)-скорость второго поезда

Answer 3

Problem Analysis

Two trains are traveling towards each other from different stations. The distance between them is 385 km, and they meet after 5 hours. The speed of one train is given as 40 km/h. We need to find the speed of the second train.

Solution

Let's assume the speed of the second train is x km/h.

We can use the formula distance = speed × time to find the distance traveled by each train.

For the first train: - Speed = 40 km/h - Time = 5 hours - Distance = 40 km/h × 5 hours = 200 km

For the second train: - Speed = x km/h - Time = 5 hours - Distance = x km/h × 5 hours = 5x km

Since the total distance traveled by both trains is 385 km, we can write the equation:

200 km + 5x km = 385 km

Simplifying the equation:

5x km = 385 km - 200 km 5x km = 185 km

Dividing both sides by 5:

x km = 185 km / 5 x km = 37 km/h

Therefore, the speed of the second train is 37 km/h.

Answer

The speed of the second train is 37 km/h.
