Question

Аня и Оля вышли одновременно из своих домов и пошли в школу через 15 минут Аня догнала Юлю какое расстояние между домами девочек если Аня шла со скоростью 80 м минуту а Оля со скоростью 60 м минуту

Answer 1

1)80×15=1200(м)-прошлаАня
2)60×15=900(м)-прошла Оля
3)1200+900=2100(м)-между домами

Answer 2

 1) 80 м/мин х 15 мин =  1200м -    прошла за 15 мин. Аня

 

     2) 65 м/мин х 15 мин =  975 м - прошла до встречи Оля

 

     3) 1200 м - 975 м =        225 м - расстояние между домами Ани и Оли.

 

2.  1) 24 : 6 х 2 =   8 мин  -   решала уравнение

 

     2) 24 : 6 х 3 = 12 мин -  решала задачи

 

     3) 24 - ( 8 + 12 ) = 24 - 20 = 4 мин -  делала проверку вычислений

 

3.  Исходя из условия, можна решить только так ;

 

      1)  7 - 5 = 2 -   в уборке принимали участие на 2 девочки больше

     Эти 2 девочки вымыли 4 стола, значит, одна девочка вымыла:   2) 4 : 2 = 2 стола

 

     Следовательно, каждый ученик вымыл по 2 стола. Тогда:

       3)  ( 5 + 7 ) х 2 = 12 х 2 = 24 - стола в классе

Answer 3

Problem Analysis

We are given that Anya and Olya left their homes simultaneously and walked to school. After 15 minutes, Anya caught up with Yulia. We need to find the distance between the girls' homes, given that Anya walks at a speed of 80 m/minute and Olya walks at a speed of 60 m/minute.

Solution

Let's assume that the distance between the girls' homes is d meters. Since Anya walks faster than Olya, she will cover more distance in the same amount of time. Let's calculate the time it takes for Anya to catch up with Yulia.

Anya's speed is 80 m/minute, and Olya's speed is 60 m/minute. Anya catches up with Yulia after 15 minutes, so the time taken by Anya to catch up is also 15 minutes.

We can use the formula distance = speed × time to calculate the distance traveled by Anya and Olya.

The distance traveled by Anya is given by 80 × 15 = 1200 meters.

The distance traveled by Olya is given by 60 × 15 = 900 meters.

Since Anya caught up with Yulia, the distance traveled by Anya is equal to the distance between the girls' homes plus the distance traveled by Olya.

Therefore, we can write the equation 1200 = d + 900.

Simplifying the equation, we find d = 1200 - 900 = 300 meters.

So, the distance between the girls' homes is 300 meters.

Answer

The distance between the girls' homes is 300 meters.
