Question

Первый станок выпускает 15 деталей в минуту,а второй 12 деталей в минуту.Чтобы выполнить заказ первому станку потребовалось 3,6 мин. Сколько минут потребуется второму станку для выполнения этого же заказа?

Answer 1

15-3.6
12-x   
x=12*3.6/12=2.88
2.88

Answer 2

Calculation of Time Required for the Second Machine

To calculate the time required for the second machine to complete the same order, we can use the concept of proportionality.

Let's assume that the time required for the second machine to complete the order is x minutes.

According to the given information: - The first machine produces 15 parts per minute. - The second machine produces 12 parts per minute. - The first machine took 3.6 minutes to complete the order.

We can set up the following proportion:

15 parts/minute = 12 parts/x minutes

To solve for x, we can cross-multiply and solve the equation:

15x = 12 * 3.6

Simplifying the equation:

15x = 43.2

Dividing both sides by 15:

x = 43.2 / 15

Calculating the value of x:

x ≈ 2.88 minutes

Therefore, the second machine will require approximately 2.88 minutes to complete the same order.
