Question

Два мастера работают на фабрике елочных украшений один из них работал 12 дней по 7 часов в день а другой 10 дней по 8 часов и вместе они расписали на 2880 елочных шаров сколько шаров в час расписывал первый мастер если второй расписывал по 15 шаров в час

Answer 1

1.12*7=84(ч) работал 1 мастер.
2.10*8=80 (ч) работал 2 мастер.
3. 15*80=1200 шаров расписал 2 мастер.
4.2880-1200=1680 расписал 1 мастер,
5.1680:84=20 шаров расписывал 1 мастер в час.

Answer 2

Calculation of the First Master's Painting Rate

To calculate the number of ornaments painted per hour by the first master, we need to determine the total number of hours worked by both masters and the total number of ornaments painted.

The first master worked for 12 days, with 7 hours of work per day, resulting in a total of 84 hours of work.

The second master worked for 10 days, with 8 hours of work per day, resulting in a total of 80 hours of work.

Together, they painted a total of 2880 ornaments.

To find the painting rate of the first master, we can divide the total number of ornaments painted by the total number of hours worked by both masters:

2880 ornaments / (84 hours + 80 hours) = 2880 ornaments / 164 hours = 17.56 ornaments per hour

Therefore, the first master painted approximately 17.56 ornaments per hour.

Please note that the second master's painting rate of 15 ornaments per hour is not relevant to the calculation of the first master's painting rate.
