Question

Собака погналась за кошкой, когда расстояние между ними было 120 м. Через какое время она догонит кошку, если кошка пробегает за 1 мин 320 м, а собака 350 м? Помогите, пж

Answer 1

ответ:(350-320)=30(м) - собака сокращает расстояние 120/30=4 (мин) - за столько она бы догнала кошку

И да я не могу почему-то сфоткать...

Answer 2

Calculation of Time for the Dog to Catch the Cat

To calculate the time it takes for the dog to catch the cat, we need to determine the relative speed between the two animals.

Given: - Distance between the dog and the cat when the dog starts chasing: 120 m - Cat's speed: 320 m/min - Dog's speed: 350 m/min

To find the relative speed, we subtract the cat's speed from the dog's speed:

Relative speed = Dog's speed - Cat's speed

Let's calculate the relative speed:

Relative speed = 350 m/min - 320 m/min = 30 m/min

Now, we can calculate the time it takes for the dog to catch the cat by dividing the initial distance between them by the relative speed:

Time = Distance / Relative speed

Time = 120 m / 30 m/min = 4 min

Therefore, it will take the dog 4 minutes to catch the cat.

Note: The above calculation assumes that both the dog and the cat maintain a constant speed throughout the chase and that there are no other factors affecting their speeds or the distance between them.
