Question

Охотничьи собаки почувствовали волка когда расстояние между ними было 200 м и бросились за ним в погоню. Скорость волка 917 м/мин,а скорость собаки 960 м/мин. Успеют ли собаки догнать волка за 4 минуты!!! ПОКАЗАТЬ РЕШЕНИЕ!!!!!

Answer 1

960-917=43м разница в скорости
43*4=172м сократится дистанция за 4 мин
200-172=28м останется
Ответ : нет, не успеют. Расстояние между ними будет 28м

Answer 2

Problem Analysis

We are given that hunting dogs sensed a wolf when the distance between them was 200 m and started chasing it. The speed of the wolf is 917 m/min, and the speed of the dogs is 960 m/min. We need to determine if the dogs will be able to catch up to the wolf within 4 minutes.

Solution

To solve this problem, we can calculate the distance covered by both the wolf and the dogs in 4 minutes and compare them.

Let's calculate the distance covered by the wolf in 4 minutes: - Speed of the wolf = 917 m/min - Time = 4 minutes - Distance covered by the wolf = Speed * Time = 917 m/min * 4 min = 3668 meters

Now, let's calculate the distance covered by the dogs in 4 minutes: - Speed of the dogs = 960 m/min - Time = 4 minutes - Distance covered by the dogs = Speed * Time = 960 m/min * 4 min = 3840 meters

Since the distance covered by the dogs (3840 meters) is greater than the distance covered by the wolf (3668 meters), the dogs will be able to catch up to the wolf within 4 minutes.

Conclusion

Based on the calculations, the hunting dogs will be able to catch up to the wolf within 4 minutes.
