Question

Первый станок отштампует требуемое число деталей за 5 ч, а второй -за 7ч.Сколько деталей в час штампует первый станок,если второй штампует в час на 100 деталей меньше,чем первый?

Answer 1

Первый станок отштампует
х - все задание
x/5 - штампует в час 1 станок
x/7 - штампует в час 2 станок
x/5-x/7=100
x=1750
Первый штампует в час 1750/5=350 деталей

Answer 2

Calculation of Production Rate

To calculate the number of parts produced per hour by the first stamping machine, we need to know the production rates of both machines and the difference in their production rates.

Let's assume that the first stamping machine produces x parts per hour. According to the given information, the second stamping machine produces 100 parts per hour less than the first machine. Therefore, the production rate of the second machine can be expressed as (x - 100) parts per hour.

We are also given that the first machine can produce the required number of parts in 5 hours, and the second machine can produce the same number of parts in 7 hours.

Calculation Steps

To find the production rate of the first machine, we can set up the following equation based on the given information:

5x = 7(x - 100)

Let's solve this equation to find the value of x.

5x = 7x - 700

2x = 700

x = 350

Therefore, the first stamping machine produces 350 parts per hour.

Answer

The first stamping machine produces 350 parts per hour, given that the second machine produces 100 parts per hour less than the first machine.
