Question

Как решить задачу за 4 класс, чтобы было понятно ребенку. Первая пчела вылетела из улья со скоростью 8 м/с, через 30 с вылетела вторая пчела со скоростью 9 м/с. Через сколько времени вторая догонит первую?

Answer 1

Ну как есть так и объясняй  просто сделай так чтоб ребёнок представлял всё это ну или какие нибудь  похожие задачи в классе может делали ...1)8*30=240м пролетела первая пчела (расстояние между пчелами)

2) 9-8=1 м/с - скорость, с котрой вторая пчела догоняет первую

3) 240:1=240 с=240:60=4 минуты - за 4 минуты догонит

Ответ: 240 секунд или 4 минуты

Answer 2

Solving the Problem for a 4th Grader

To solve this problem, we can use the concept of distance, speed, and time. We know that distance = speed × time. In this case, both bees are traveling the same distance, so we can set up an equation to find the time it takes for the second bee to catch up to the first bee.

Let's denote: - Speed of the first bee as 8 m/s - Speed of the second bee as 9 m/s - Time taken by the second bee to catch up to the first bee as t (in seconds)

We can use the formula: distance = speed × time to solve for the time it takes for the second bee to catch up to the first bee.

Calculating the Time

The distance traveled by both bees will be the same when the second bee catches up to the first bee. Therefore, we can set up the equation:

Distance traveled by the first bee = Distance traveled by the second bee

Using the formula distance = speed × time, we can write the equation as:

8t = 9(t - 30)

Solving for t will give us the time it takes for the second bee to catch up to the first bee.

Solution

t = 270 seconds

So, the second bee will catch up to the first bee after 270 seconds.
