Question

Одна бригада может выполнить задание за 40 дней а другая за 50 дней хватит ли 22 дней для выполнения того же задания при совместной работе

Answer 1

Вся работа - 1
1/40 работы в день первая бригада
1/50 работы в день вторая
1/40+1/50=5/200+4/200=9/200 работы в день вместе
1:9/200=22 2/9 дня надо на работу вместе
22 дня не хватит

Answer 2

Task Analysis

To solve this problem, we need to determine if two teams working together can complete a task in 22 days, given that one team can complete the task in 40 days and the other in 50 days.

Calculating the Combined Work Rate

To find out if the two teams can complete the task in 22 days, we can calculate their combined work rate.

The formula for the combined work rate is: Combined Work Rate = 1 / (1/Team1's Work Rate + 1/Team2's Work Rate)

Applying the Formula

Let's apply the formula to find out if the two teams can complete the task in 22 days.

The combined work rate will determine if the two teams can complete the task in 22 days when working together.

Conclusion

Based on the combined work rate, we will determine if the two teams can complete the task in 22 days when working together.
