Question

Собака гонится за зайцем со скоростью 750м в мин а заяц убегает от нее со скоростью 800 м в мин с какой скоростью изменяется растояние между собакой и зайцем каким оно станет через 8 мин если сейчас между ними 600 м

Answer 1

Смотри каждую минуту расстояние увиличивается на 50м.Через 8 минут расстояние будет 50х8+600=1000метров 

Answer 2

1) 800-750=50(м)
2)50*8=400(м)
3)400+600=1000(м)
Ответ:1000метров будет растояние через 8 минут

Answer 3

Calculation of the Changing Distance between the Dog and the Hare

To calculate the changing distance between the dog and the hare, we need to consider their relative speeds. The dog is chasing the hare with a speed of 750 m/min, while the hare is running away from the dog with a speed of 800 m/min.

Let's denote the initial distance between the dog and the hare as D₀ = 600 m. We want to find the distance between them after 8 minutes.

To calculate the changing distance, we can use the formula:

Distance = Initial Distance + (Relative Speed × Time)

Let's substitute the given values into the formula:

Distance = 600 m + ((800 m/min - 750 m/min) × 8 min)

Simplifying the equation:

Distance = 600 m + (50 m/min × 8 min)

Distance = 600 m + 400 m

Distance = 1000 m

Therefore, the distance between the dog and the hare will be 1000 meters after 8 minutes.

Please note that the above calculation assumes constant speeds for both the dog and the hare. Additionally, the calculation does not take into account any changes in acceleration or deceleration during the chase.
