Question

5 станков-автоматов при одновременной работе могут выполнить некоторый заказ за 12часов. За сколько часов будет выполнен тот же заказ при одновременной работе 8 таких же станков-автоматов?

Answer 1

Надо 8 поделить на  5 и мы получим 1,6 раз это будет  увеличение

станков

12 поделим на 1,6 получим 7,5 -это часов потребуется для выполнения

 того же заказа восьмью станками.

Ответ: 7.5 часов

Answer 2

1- вся работа
1:5:12=1/60- производительность одного станка
1/60*8=8/60=2/15- производительность 8 станков
1:2/15=1*15/2=7,5ч- За столько часов будет выполнен заказ

Answer 3

Calculation of Time to Complete the Order

To determine the time it takes to complete the same order with 8 identical automatic machines working simultaneously, we can use the information provided.

According to the given information, 5 machines working together can complete the order in 12 hours. We need to find out how long it will take for 8 machines to complete the same order.

Let's assume that the time it takes for 5 machines to complete the order is represented by T hours. Therefore, we can set up the following equation:

5T = 12

To find the time it takes for 8 machines to complete the order, we can use the equation:

8T = ?

To solve for T, we can rearrange the equation:

T = 12 / 5

Now, we can substitute the value of T into the equation for 8 machines:

8 * (12 / 5) = ?

Simplifying the equation:

96 / 5 = ?

Therefore, it will take approximately 19.2 hours for 8 identical automatic machines working simultaneously to complete the same order.

Answer:

If 5 machines working together can complete the order in 12 hours, then it will take approximately 19.2 hours for 8 machines to complete the same order when working simultaneously.
