Question

315. Собака усмотрела в 360 метрах зайца, который пробегает за 2 минуты 1060 метров. Спрашивается, за какое время догонит зайца собака, пробе. гающая за 5 минут 2770 метров?пжж помогите​

Answer 1

Ответ:

Пошаговое объяснение:

1060 : 2= 530м/ мин скорость зайца

2770 : 5= 554 м/мин скорость собаки

554 - 530= 24 м/мин скорость сближения

360 : 24 = 15 мин за такое время догонит зайца собака

Answer 2

To solve this problem, we can use the formula: speed = distance / time.

Let's calculate the speed of the rabbit first. The rabbit covers a distance of 1060 meters in 2 minutes. Using the formula, we can calculate its speed as follows:

Speed of the rabbit = 1060 meters / 2 minutes = 530 meters per minute. [[1]]

Now, let's calculate the speed of the dog. The dog covers a distance of 2770 meters in 5 minutes. Using the formula, we can calculate its speed as follows:

Speed of the dog = 2770 meters / 5 minutes = 554 meters per minute. [[2]]

Since the dog's speed is greater than the rabbit's speed, we can conclude that the dog will eventually catch up to the rabbit.

To find out how long it will take for the dog to catch up to the rabbit, we can use the formula: time = distance / speed.

Let's calculate the time it will take for the dog to catch up to the rabbit. The distance between the dog and the rabbit is 360 meters. Using the formula, we can calculate the time as follows:

Time = 360 meters / (554 meters per minute - 530 meters per minute) = 360 meters / 24 meters per minute = 15 minutes.

Therefore, it will take the dog 15 minutes to catch up to the rabbit.
