Question

Лисица гонится за косулей.Скорость лисицы 11м в секуну,а скорость косули 9 метров в секунду .Сейчас между ними 300метров.на аком расстоянии от косули будет лисица через 40 секунд?Через сколько времини она догонит косулю?жду ответ !!!

Answer 1

11cек -9сек=2 сек Скорость с которой уменьшается расстояния 
2*40=80 метров – величина сближения 
300-80=220 метров между животными через 40с. 

Answer 2

Calculation of Distance and Time for the Fox to Catch the Deer

To calculate the distance and time it will take for the fox to catch up to the deer, we can use the given speeds of the fox and the deer, as well as the initial distance between them.

Given: - Speed of the fox: 11 m/s - Speed of the deer: 9 m/s - Initial distance between them: 300 meters

To find the distance between the fox and the deer after 40 seconds, we can use the formula:

Distance = Speed × Time

Let's calculate the distance between the fox and the deer after 40 seconds:

Distance = Speed of the deer × Time

Distance = 9 m/s × 40 s

Distance = 360 meters

Therefore, after 40 seconds, the distance between the fox and the deer will be 360 meters.

To find out how long it will take for the fox to catch up to the deer, we need to calculate the time it takes for the fox to cover the initial distance between them (300 meters) plus the additional distance of 360 meters.

Let's calculate the time it will take for the fox to catch up to the deer:

Time = Distance / Speed of the fox

Time = (300 m + 360 m) / 11 m/s

Time = 660 m / 11 m/s

Time = 60 seconds

Therefore, it will take the fox 60 seconds to catch up to the deer.

Please note that these calculations assume constant speeds for both the fox and the deer, and do not take into account any other factors that may affect their movements.
