Question

ПОМОГИТЕ ПОЖАЛУЙСТА, С ОБЪЯСНЕНИЕМ!!!! Собака гонится за зайцем. За минуту собака делает 200 скачков, что составляет 2/3 числа скачков, которые делает за минуту заяц. Длина заячьего скачка равна 90 см, что составляет 3/5 длинны собачьего скачка. С какими скоростями бегут собака и заяц? Каким станет расстояние между ними через 5 минут, если сейчас заяц впереди собаки на 500 метров ​

Answer 1

Пошаговое объяснение:

Собака-200 скачков в минуту,что составляет 2/3 числа скачков зайца

Заяц-? скачков в минуту

Скачок зайца-90 см что составляет 3/5 длинны собачьего скачка.

Собака -? скачков в минуту

1 вопрос" с какими скоростями бегут Собака и Заяц ?"

2 вопрос"Каким станет расстояние между ними через час, если Заяц впереди Собаки на 500 метров

1)200=2/3=300-200=100 скачков составляет Заяц в минуту.

2)90=3/5=90:3=30= 1/5 =30*5=150 см Скачок Собаки

3)500*100=50000 см расстояние между ними

4)150-90=60(скорость сближения=V

5)50000-(5*60)=49700 см через 5 минут будет между ними.

Answer 2

Problem Analysis

We are given the following information: - The dog makes 200 jumps in one minute, which is 2/3 of the number of jumps made by the hare in one minute. - The length of the hare's jump is 90 cm, which is 3/5 of the length of the dog's jump. - The hare is currently 500 meters ahead of the dog.

We need to find: - The speeds at which the dog and the hare are running. - The distance between them after 5 minutes.

Solution

Let's start by finding the number of jumps made by the hare in one minute. We know that the dog makes 200 jumps, which is 2/3 of the number of jumps made by the hare. Therefore, we can set up the following equation:

(2/3) * x = 200

Solving this equation, we find that x = 300. So, the hare makes 300 jumps in one minute.

Next, let's find the length of the dog's jump. We know that the length of the hare's jump is 90 cm, which is 3/5 of the length of the dog's jump. Therefore, we can set up the following equation:

(3/5) * y = 90

Solving this equation, we find that y = 150. So, the length of the dog's jump is 150 cm.

Now, let's find the speed at which the dog is running. We know that the dog makes 200 jumps in one minute, and the length of each jump is 150 cm. Therefore, the dog covers a distance of 200 * 150 = 30,000 cm in one minute. To convert this to meters, we divide by 100, so the dog's speed is 300 meters per minute.

Similarly, let's find the speed at which the hare is running. We know that the hare makes 300 jumps in one minute, and the length of each jump is 90 cm. Therefore, the hare covers a distance of 300 * 90 = 27,000 cm in one minute. To convert this to meters, we divide by 100, so the hare's speed is 270 meters per minute.

Now, let's find the distance between the dog and the hare after 5 minutes. We know that the hare is currently 500 meters ahead of the dog. In 5 minutes, the dog will cover a distance of 5 * 300 = 1500 meters, and the hare will cover a distance of 5 * 270 = 1350 meters. Since the hare is ahead of the dog, we subtract the distance covered by the hare from the distance covered by the dog and add the initial distance between them:

Distance = 1500 - 1350 + 500 = 650 meters

Therefore, the distance between the dog and the hare after 5 minutes will be 650 meters.

To summarize: - The dog is running at a speed of 300 meters per minute. - The hare is running at a speed of 270 meters per minute. - The distance between the dog and the hare after 5 minutes will be 650 meters.

Note: The above solution is based on the information provided in the question.
