Question

Колобок катится навстречу Лисе. Сейчас между ними 900м. Скорость Колобка 70м/мин, а скорость Лисы 80м/мин. Какое расстояние будет между ними через 2 минуты? Через сколько минут они встретятся?

Answer 1

70+80=150 (м/мин) - скорость сближения Колобка и Лисы.а) 900-150·2=900-300=600 (м) - расстояние между ними через 2 минуты.б) 900:150=6 (мин) - встретятся Колобок и Лиса.Ответ: 600 метров расстояние между ними через 2 минуты; через 6 минут они встретятся.

Answer 2

70+80=150 м/мин скорость сближения колобка и лисы                                             900-(150*2)=900-300=600 м расстояния через 2 минуты                                        900:150=6 мин (через 6 минут встретятся

Answer 3

Calculation of Distance after 2 Minutes:

To calculate the distance between the rolling Kolobok and the Fox after 2 minutes, we need to determine how far each of them will travel in that time.

Given: - Distance between them currently: 900 meters - Kolobok's speed: 70 meters per minute - Fox's speed: 80 meters per minute

To find the distance between them after 2 minutes, we can calculate the distance traveled by each of them separately and then subtract the distance traveled by Kolobok from the initial distance between them.

Distance traveled by Kolobok in 2 minutes: 70 meters/minute * 2 minutes = 140 meters [[1]].

Distance traveled by the Fox in 2 minutes: 80 meters/minute * 2 minutes = 160 meters [[1]].

Therefore, the distance between them after 2 minutes will be: 900 meters - 140 meters = 760 meters.

Calculation of Meeting Time:

To calculate the time it takes for the rolling Kolobok and the Fox to meet, we need to determine the time it takes for them to cover the initial distance between them.

Given: - Distance between them currently: 900 meters - Kolobok's speed: 70 meters per minute - Fox's speed: 80 meters per minute

To find the meeting time, we can divide the initial distance between them by the combined speed of Kolobok and the Fox.

Meeting time = Distance / (Kolobok's speed + Fox's speed) Meeting time = 900 meters / (70 meters/minute + 80 meters/minute) Meeting time = 900 meters / 150 meters/minute Meeting time = 6 minutes

Therefore, they will meet in 6 minutes.
