Question

трое маляров могут закончить работу за 5 дней.Для ускорения работы добавили еще двух маляров.За какое время они закончат работу,если все маляры рабтают с одинаковой производительностью?

Answer 1

3х5=15-объем работы,которую должны сделать маляры
3+2=5-новое количество маляров
15/5=3дня

Answer 2

Обьем работы которую должны сделать маляры=3х5=15 (человеко/дней) . Если добавить еще два маляра, то получится 15(ч/д) делить на 3+2=5 (новое кол-во маляров).ответ:3 дня

Answer 3

Calculating Time to Complete Work with Additional Workers

To calculate the time it will take for the additional two painters to complete the work, we can use the formula:

Total Work = Work Rate × Time

Given that three painters can finish the work in 5 days, we can calculate the work rate of each painter and then use it to find the time required for five painters to finish the same work.

The work rate of three painters can be calculated as follows: 3 painters × 5 days = 15 painter-days

Now, we can use the work rate to find the time required for five painters to finish the work.

Calculation

Using the work rate of 15 painter-days for three painters, we can find the time required for five painters as follows:

15 painter-days ÷ 5 painters = 3 days

Therefore, with the addition of two more painters, they will be able to finish the work in 3 days if all the painters work with the same productivity.

This calculation assumes that the productivity of each painter remains constant when additional workers are added.
