Question

6 маляров могут покрасить спорт зал за 16.5 ч. За какое время сделают эту работу 10 маляров? Ответ записать в часах и минутах.

Answer 1

Получается, что вся работа равна 16.5 * 6, и теперь это подели на 10 = 9.9 часов = 9 часов 54 минуты

Answer 2

Calculation

To calculate the time it takes for 10 painters to paint a sports hall, we can use the concept of man-hours.

Given that 6 painters can paint the sports hall in 16.5 hours, we can calculate the total man-hours required for the job:

6 painters x 16.5 hours = 99 man-hours.

Now, to find out how long it would take 10 painters to complete the same job, we can divide the total man-hours by the number of painters:

99 man-hours / 10 painters = 9.9 hours.

Therefore, it would take 10 painters approximately 9 hours and 54 minutes to complete the painting job.

Answer

The job can be completed by 10 painters in approximately 9 hours and 54 minutes.
