Question

Помогите решить задачу! По лесной тропинке навстречу друг другу одновременно выбежали два ёжика. Скорость одного 67м/мин а скорость второго на 6м/мин больше. Через сколько они встретятся если между ними 560м?

Answer 1

1)Найдем скорость второго ёжика      67+6=73м/мин
2)Найдем их общую скорость         67м/мин+73м/мин=140м/мин
3)Находим время          560м:140м/мин=4мин
Ответ: 4 мин.

Answer 2

Problem Analysis

We are given that two hedgehogs are running towards each other on a forest path. The speed of one hedgehog is 67 m/min, while the speed of the other hedgehog is 6 m/min faster. The distance between them is 560 m. We need to find out how long it will take for them to meet.

Solution

To solve this problem, we can use the formula: time = distance / relative speed.

Let's assume the speed of the second hedgehog is x m/min. Since the speed of the second hedgehog is 6 m/min faster than the first hedgehog, its speed can be represented as (67 + 6) m/min.

The relative speed of the two hedgehogs is the sum of their speeds, which is (67 + 6) m/min.

The time it takes for them to meet is given by the formula: time = distance / relative speed.

Substituting the given values, we have: time = 560 m / (67 + 6) m/min.

Now, let's calculate the time it takes for the hedgehogs to meet.

Calculation

Using the formula time = distance / relative speed, we can calculate the time it takes for the hedgehogs to meet:

time = 560 m / (67 + 6) m/min.

Simplifying the expression, we have: time = 560 m / 73 m/min.

Calculating the value, we get: time ≈ 7.671 m/min.

Therefore, it will take approximately 7.671 minutes for the two hedgehogs to meet.

Answer

It will take approximately 7.671 minutes for the two hedgehogs to meet.

Note: The answer has been calculated based on the given information and the formula for time.
