Question

Катя и Маша пошли в лес. По дороге девочки съели банан, а кожуру бросили на землю. Сколько лет будет Кате, когда оставленный мусор разложится, если Катя на 8 лет старше Маши, а два года назад ей было втрое больше ,чем Маше? ( возможно банан разлагается 2 года).

Answer 1

х лет Маше

х+8 лет Кате 

(х-2) *3=х+8-2

3х-6=х+6

2х=12

х=6

6+8=14 лет Кате

Если банан разлагается 2 года, то

14+2=16 лет будет Катечерез 2 года 

Answer 2

Calculation of the Time it Takes for the Banana Peel to Decompose

To calculate the time it takes for the banana peel to decompose, we need to consider the information provided in the question. Let's break it down step by step:

1. We are given that Katya is 8 years older than Masha. 2. Two years ago, Katya's age was three times Masha's age.

Let's assign variables to represent the ages of Katya and Masha:

- Let K represent Katya's current age. - Let M represent Masha's current age.

Based on the information given, we can set up the following equations:

1. K = M + 8 (Katya is 8 years older than Masha) 2. K - 2 = 3(M - 2) (Two years ago, Katya's age was three times Masha's age)

Now, let's solve these equations to find the current ages of Katya and Masha:

From equation 1, we can substitute K with M + 8 in equation 2:

(M + 8) - 2 = 3(M - 2) M + 6 = 3M - 6 2M = 12 M = 6

Substituting M = 6 into equation 1, we can find Katya's current age:

K = 6 + 8 K = 14

Therefore, Katya is currently 14 years old and Masha is 6 years old.

Now, let's calculate the time it takes for the banana peel to decompose. According to the information provided, the banana peel decomposes in 2 years.

Therefore, when the banana peel decomposes, Katya will be 14 + 2 = 16 years old.

So, when the abandoned trash decomposes, Katya will be 16 years old.

Please note that the time it takes for a banana peel to decompose can vary depending on various factors such as environmental conditions. The given time frame of 2 years is an approximation.
