Question

со станции вышел поезд со скоростью 60км/ч.Через некоторое время с той же станции и в том же направлении вышел второй поезд.С какой скоростью он должен ехать,чтобы расстояние между ними с момента выезда второго поезда не менялосьПЛЛЛЛЛЛИИИИИЗЗЗ ПОМОГИИИТЕ ДАМ БАЛЛЫ ТОЛЬКО РАСПЕШИТЕ ПО ДЕЙСТВИЯМ

Answer 1

Также со скоростью 60км/ч, чтобы расстояние между ними не менялось, ведь если скорость будет больше, то поезд начнет догонять, а если меньше, то отставать.

Answer 2

Problem Analysis

We have two trains that start from the same station and travel in the same direction. The first train has a speed of 60 km/h. We need to determine the speed at which the second train should travel in order for the distance between the two trains to remain constant after the second train departs.

Solution

Let's assume that the second train travels at a speed of x km/h. Since both trains are traveling in the same direction, the relative speed between the two trains will be the difference between their speeds.

The relative speed between the two trains is given by the formula:

Relative Speed = Speed of Second Train - Speed of First Train

To keep the distance between the two trains constant, the relative speed should be zero. Therefore, we can set up the following equation:

x - 60 = 0

Solving this equation will give us the speed at which the second train should travel.

Calculation

To find the speed of the second train, we solve the equation:

x - 60 = 0

Adding 60 to both sides of the equation, we get:

x = 60

Therefore, the second train should travel at a speed of 60 km/h in order for the distance between the two trains to remain constant.

Answer

The second train should travel at a speed of 60 km/h in order for the distance between the two trains to remain constant.
