Question

Собака гонится за зайцем со скоростью 750 м/мин а заяц убегает от нее со скоростью 800м/мин с какой скоростью изменяется расстояние между собакой и зайцем? Каким оно станет через 8 мин если сейчас между собакой и зайцем 600 м

Answer 1

расстояние между ними изменяется со скоростью 
800-750=50м/мин 
за 8 минут расстояние будет 
8*50=400м 
400+600  равно 1000

Answer 2

Calculation of the Rate of Change of Distance

To determine the rate at which the distance between the dog and the hare is changing, we need to calculate the relative speed between them. The relative speed is the difference between their individual speeds. In this case, the dog is running at a speed of 750 m/min, while the hare is running at a speed of 800 m/min.

To find the rate at which the distance is changing, we subtract the hare's speed from the dog's speed:

Relative speed = Dog's speed - Hare's speed Relative speed = 750 m/min - 800 m/min Relative speed = -50 m/min

The negative sign indicates that the distance between the dog and the hare is decreasing.

Calculation of the Distance after 8 Minutes

To calculate the distance between the dog and the hare after 8 minutes, we need to use the formula:

Distance = Initial distance + (Relative speed * Time)

Given that the initial distance between the dog and the hare is 600 m, and the relative speed is -50 m/min, we can substitute these values into the formula:

Distance = 600 m + (-50 m/min * 8 min) Distance = 600 m - 400 m Distance = 200 m

Therefore, after 8 minutes, the distance between the dog and the hare will be 200 meters.
