Question

за 8 часов маляр красит 32 окна а его ученик в 2 раза меньше сколько они покрасят за 13 часов если будут работать вместе

Answer 1

32:8=4(ок/ч)

4:2=2(ок/ч)

4+2=6

13*6=78(ок/ч)

Answer 2

1) 32:8=4 (окна) - красит за 1 час маляр

2) 4:2=2 (окна) - красит за 1 час ученик

3) 4+2=6 (окон) - красят за 1 час вместе

4) 6*13=78 (окон)

Ответ: 78 окон покрасят за 13 часов,  если  будут  работать  вместе

Answer 3

Calculation of Painting Speed

To calculate how many windows the painter and his apprentice can paint together in 13 hours, we first need to determine the painting speed of each individual.

According to the given information, the painter can paint 32 windows in 8 hours, while his apprentice can paint half as many windows in the same amount of time.

Let's calculate the painting speed of each individual:

- The painter's painting speed: 32 windows / 8 hours = 4 windows per hour. - The apprentice's painting speed: (1/2) * 32 windows / 8 hours = 2 windows per hour.

Calculation of Combined Painting Speed

To determine how many windows they can paint together in 13 hours, we need to calculate their combined painting speed.

The combined painting speed is the sum of their individual painting speeds:

- Combined painting speed: 4 windows per hour + 2 windows per hour = 6 windows per hour.

Calculation of Total Number of Windows Painted

To find out how many windows they can paint together in 13 hours, we multiply their combined painting speed by the number of hours they work:

- Total number of windows painted: 6 windows per hour * 13 hours = 78 windows.

Therefore, if the painter and his apprentice work together for 13 hours, they will be able to paint 78 windows.
