Question

Собака бросилась догонять лисица, когда между ними было 185 м. Через 3 мин лисица юркнула в нору. На каком расстоянии от неё была в этот момент собака, если скорость собаки 540 м/мин, а скорость лисицы 480 м/мин.

Answer 1

(540*3)+(480*3)+185=3245(м)-расстояние между ними когда лиса прыгнула в нору

Answer 2

Problem Analysis

We are given the following information: - The distance between the dog and the fox was 185 m. - After 3 minutes, the fox ran into its burrow. - The dog's speed is 540 m/min. - The fox's speed is 480 m/min.

We need to find the distance between the fox and the dog when the fox ran into its burrow.

Solution

To find the distance between the fox and the dog when the fox ran into its burrow, we need to calculate the distance covered by the dog in 3 minutes.

The distance covered by an object can be calculated using the formula: distance = speed × time.

Using this formula, we can calculate the distance covered by the dog in 3 minutes: distance_dog = speed_dog × time = 540 m/min × 3 min = 1620 m.

Since the dog was initially 185 m away from the fox, and it covered a distance of 1620 m in 3 minutes, the distance between the fox and the dog when the fox ran into its burrow can be calculated as follows: distance_fox = initial_distance - distance_dog = 185 m - 1620 m = -1435 m.

However, a negative distance does not make sense in this context. Therefore, we can conclude that the dog did not catch up to the fox before it ran into its burrow.

Answer

The dog was 1435 meters away from the fox when the fox ran into its burrow.
