Question

Бригада из 12 человек должна была высадить цветы в парке за 4 часа,но 2 человека заболели и не пришли на работу.Сколько времени потребуется бригаде, чтобы выполнить задание? сроооооочно, заранее огромное спасибо

Answer 1

Пусть вся работа - 1,тогда один  человек за 4 часа выполняет 1/12 всей работы, а за час-  1/12:4=1/48
10 человек,соответственно,выполнят за час-  10/48;5/24
значит всю работу они выполнят : 1: 5/24=1x24/5=4  4/5 часа или 4 часа 48 мин

Answer 2

Calculation of Time Required

To calculate the time required for the team to complete the task, we need to consider the following information:

- The original task was supposed to be completed by a team of 12 people in 4 hours. - However, 2 people fell ill and did not come to work.

To find the new time required, we can use the concept of "man-hours." Man-hours represent the total number of hours worked by a team. In this case, we can calculate the man-hours required to complete the task with the available team members.

The original task required 12 people working for 4 hours, which gives us a total of 48 man-hours (12 people x 4 hours).

Since 2 people are absent, we need to subtract their man-hours from the total. Assuming each person works for the same amount of time, we can subtract 8 man-hours (2 people x 4 hours) from the total.

Therefore, the new total man-hours required to complete the task with the available team members is 40 man-hours (48 man-hours - 8 man-hours).

To find the new time required, we divide the total man-hours by the number of people in the team. In this case, we divide 40 man-hours by the remaining 10 team members.

The new time required can be calculated as follows:

40 man-hours ÷ 10 people = 4 hours

Therefore, with the available team members, it will still take the team 4 hours to complete the task.
