Question

Собака гонится за лисицей со скоростью 750м/мин,а лисица убегает от неё со скоростью 800м/мин.С какой скоростью изменяется расстояние между ними?Каким оно станет через 8 мин,если сейчас между ними 600 м

Answer 1

Движение с удалением:

 

v уд = 800 - 750 = 50 м\мин

 

Соответственно, через 8 мин расстояние будет

 

600+ 50*8 = 1км

 

Детская задача. В чем сложность то? Оо

Answer 2

800-750=50м/мин-изменяется расстояние

750*8=6000м-пробежала собака

800*8=6400м-пробежала лисица

600+(6400-6000)=1000м-расстояние между ними через 8мин

Answer 3

Calculation of the Rate of Change of Distance

To determine the rate at which the distance between the dog and the fox is changing, we can subtract the speeds at which they are moving. The dog is moving at a speed of 750 m/min, while the fox is moving at a speed of 800 m/min. By subtracting these two speeds, we can find the rate at which the distance between them is changing.

The rate of change of distance is given by the formula:

Rate of change of distance = Speed of the fox - Speed of the dog

Substituting the given values:

Rate of change of distance = 800 m/min - 750 m/min

Calculating the difference:

Rate of change of distance = 50 m/min.

Calculation of the Distance After 8 Minutes

To calculate the distance between the dog and the fox after 8 minutes, we can use the formula:

Distance = Initial Distance + (Rate of change of distance * Time)

Given that the initial distance between them is 600 m and the rate of change of distance is 50 m/min, we can calculate the distance after 8 minutes:

Distance = 600 m + (50 m/min * 8 min)

Calculating the distance:

Distance = 600 m + 400 m

Distance = 1000 m

Therefore, the distance between the dog and the fox will be 1000 meters after 8 minutes
