Question

Из двух поселков расстояние между которыми 675км навстречу друг другу одновременно выехали два поезда и встретились через 5 часов скорость первого 65 километров в час найди скорость второго

Answer 1

Км 675-325=350 350/5=70 км/ч

Answer 2

1)675:5=135 (км/ч)-Скорость 1 поезда                                                               2)135-65=70 (км/ч)-Скорость 2 поезда.

Answer 3

Problem Analysis

We are given that two trains start simultaneously from two different towns and meet after 5 hours. The distance between the towns is 675 km. The speed of the first train is 65 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 know that the distance traveled by both trains is the same, as they meet each other. Therefore, the distance traveled by the first train is equal to the distance traveled by the second train.

The distance traveled by the first train can be calculated using the formula: distance = speed × time.

For the first train: Distance = Speed × Time 675 km = 65 km/h × 5 hours

Now, let's calculate the distance traveled by the second train using the same formula: Distance = Speed × Time 675 km = x km/h × 5 hours

Since the distances traveled by both trains are equal, we can set up the following equation: 65 km/h × 5 hours = x km/h × 5 hours

Simplifying the equation, we get: 65 × 5 = x × 5

Now, we can solve for x: x = (65 × 5) / 5

Calculation

Let's calculate the value of x:

x = (65 × 5) / 5 x = 65

Answer

The speed of the second train is 65 km/h.
