Question

Собака гонится за лисой со скоростью 700 м/мин , а лиса убегает от неё со скоростью 850 м/мин . Сейчас между собакой и лисой 400м. Каким станет расстояние между ними через 7минут.

Answer 1

850-700=150, 150x7=1050, 1050+400=1450

Answer 2

850-700=150 скорость отдаления
150*7+400=1450 метров
Ответ: расстояние будет 1450 метров
(хотя собака, скорее всего, задолбается гоняться за лисой на расстоянии >км и отстанет)

Answer 3

Calculation of the Distance Between the Dog and the Fox

To calculate the distance between the dog and the fox after 7 minutes, we need to consider their speeds and the initial distance between them.

Given: - The dog's speed is 700 m/min. - The fox's speed is 850 m/min. - The initial distance between them is 400 m.

To find the distance between them after 7 minutes, we can use the formula:

Distance = Initial Distance + (Relative Speed × Time)

Let's calculate the distance between the dog and the fox after 7 minutes.

Calculation:

1. Calculate the relative speed: - The relative speed is the difference between the fox's speed and the dog's speed. - Relative Speed = Fox's Speed - Dog's Speed - Relative Speed = 850 m/min - 700 m/min - Relative Speed = 150 m/min

2. Calculate the distance between the dog and the fox after 7 minutes: - Distance = Initial Distance + (Relative Speed × Time) - Distance = 400 m + (150 m/min × 7 min) - Distance = 400 m + 1050 m - Distance = 1450 m

Answer:

The distance between the dog and the fox after 7 minutes will be 1450 meters.

Please note that the provided answer is based on the given information and calculations.
