Question

Собака бросилась догонять лису,когда между ними было 185м,через 3мин лисица юркнула в нору,на каком расстоянии от неё была в этот момент собака,если скорость собаки 540м/мин,а скорость лисы 480м/мин

Answer 1

1)540-480=60(м\мин)                                                                        2)60*3=180(м)                                                                                                    3)185-180=5(м)                                                                                               ответ:5 метров.

Answer 2

Calculating the Distance Between the Dog and the Fox

To calculate the distance between the dog and the fox when the fox entered the burrow, we can use the formula:

Distance = Speed × Time

Given: - Dog's speed = 540 m/min - Fox's speed = 480 m/min - Initial distance between them = 185 m - Time elapsed = 3 minutes

First, we calculate the distance each animal traveled in 3 minutes.

For the dog: Distance dog traveled = 540 m/min × 3 min = 1620 m

For the fox: Distance fox traveled = 480 m/min × 3 min = 1440 m

Now, we subtract the distance the fox traveled from the initial distance between them to find the distance between the dog and the fox when the fox entered the burrow.

Distance = Initial distance - Distance fox traveled Distance = 185 m - 1440 m = -1255 m

The negative distance indicates that the fox entered the burrow before the dog could catch up to it. Therefore, at the moment the fox entered the burrow, the dog was 1255 meters away from it.
