Question

Две бригады студенческого строительного отряда , работая вместе , построили кошару для овец за 12 дней . Сколько потребовалось бы дней для строительства такой же кошары каждой бригаде отдельно , если первой бригаде нужно было работать на 10 дней больше чем второй

Answer 1

12:2=6дней каждая бригада 6==6+10=16дн 16+6=22дня

Answer 2

Calculation of Construction Time for Each Brigade

To determine the number of days required for each brigade to construct a similar sheepfold separately, we can use the information provided.

Let's assume that the second brigade took x days to complete the construction.

According to the given information, the first brigade worked for 10 days longer than the second brigade. Therefore, the first brigade worked for x + 10 days.

Together, the two brigades completed the construction in 12 days.

To find the individual construction time for each brigade, we can set up the following equation:

(x + 10) + x = 12

Simplifying the equation:

2x + 10 = 12

Subtracting 10 from both sides:

2x = 2

Dividing both sides by 2:

x = 1

Therefore, the second brigade would require 1 day to construct a similar sheepfold separately, while the first brigade would require 1 + 10 = 11 days.

Please note that the above calculation assumes that the construction speed of each brigade remains constant throughout the project.
