Question

Собака погналась за лисой, находящейся от неё на расстоянии 120 м. Лиса пробегает в минуту 320 м, а собака - 350 м. На сколько метров сократится расстояние между лисой и собакой через минуту?

Answer 1

1)350-320=30(м/мин.)-скорость приближения собаки к лисице.  Ответ:30м

2)Если бы собака сидела на месте,а лиса побежала,то расстояние между ними было бы 120м+320м=440м ,но собака побежала вслед одновременно ,то расстояние между ними бдет через минуту  440м-350м=90м,на солько же оно уменшилось?  120м-90м=30м Ответ :30м 

Answer 2

1) 350 - 320 = 30(м.)

Ответ: На 30 м. сократится расстояние между лисой и собакой через минуту.!

Answer 3

Problem Analysis

We are given the following information: - The distance between the dog and the fox is 120 meters. - The fox runs at a speed of 320 meters per minute. - The dog runs at a speed of 350 meters per minute.

We need to determine how much the distance between the fox and the dog will decrease after one minute.

Calculation

To calculate the decrease in distance between the fox and the dog after one minute, we need to find the difference between the distance the fox runs and the distance the dog runs.

The fox runs at a speed of 320 meters per minute, so after one minute, it will be 320 meters closer to the dog.

The dog runs at a speed of 350 meters per minute, so after one minute, it will be 350 meters closer to the fox.

Therefore, the distance between the fox and the dog will decrease by the difference between the distances they run in one minute.

Solution

The distance between the fox and the dog will decrease by 30 meters after one minute.

Example Calculation

Let's calculate the decrease in distance between the fox and the dog after one minute using the given information.

- Distance between the fox and the dog: 120 meters - Distance the fox runs in one minute: 320 meters - Distance the dog runs in one minute: 350 meters

The distance between the fox and the dog will decrease by the difference between the distances they run in one minute.

Decrease in distance = Distance the dog runs - Distance the fox runs = 350 meters - 320 meters = 30 meters

Therefore, the distance between the fox and the dog will decrease by 30 meters after one minute.

Conclusion

After one minute, the distance between the fox and the dog will decrease by 30 meters.
