Question

В доме надо поставить ь 360 окон одна бригада это может сделать за шесть дней одна бригада это может сделать за шесть дней, а другая за 12 дней. За сколько дней они могут выполнить эту работу вместе

Answer 1

1)360:6=60окон за 1 день первая бригада
2)360:12=30окон за 1 день 2ая бригада
3)360:(60+30)=4дня

Answer 2

1)360:6=60(окон/день)-скорость первой бригады.
2)360:12=30(окон/день)-скорость второй бригады.
3)60+30=90(окон/день)-общая скорость.
4)360:90=4(дня)-за столько дней обе бригады поставят 360 окон
Ответ: за 4 дня

Answer 3

Calculating Window Installation Time

To calculate the time required for the two teams to install 360 windows, we can use the concept of work done per day by each team.

- Team 1 can install the windows in 6 days. - Team 2 can install the windows in 12 days.

To find out how long it will take for both teams to complete the work together, we can use the formula:

Total work = (Work done by Team 1 per day + Work done by Team 2 per day) * Number of days

Using this formula, we can calculate the time required for both teams to complete the installation.

The work done by each team per day can be calculated as follows: - Team 1: 1/6 of the work per day - Team 2: 1/12 of the work per day

Now, we can calculate the total time required for both teams to complete the installation.

Calculation

Total work = 360 windows

Work done by Team 1 per day = 1/6 of the total work Work done by Team 2 per day = 1/12 of the total work

Total work done per day by both teams = 1/6 + 1/12 = 3/12 + 1/12 = 4/12 = 1/3

Number of days required = Total work / (Work done per day by both teams) Number of days required = 360 / (1/3) = 360 * 3 = 1080

Therefore, both teams working together can complete the installation in 1080 days.
