Question

За 50 сек токарь изготавливает одну деталь.Сколько таких деталей он изготовит за 3 ч,если будет работать с такой же производительностью?

Answer 1

1час=60 мин     1мин=60 сек                                                                                      60*60=3600 сек в 1 часу                                                                                            3600*3=10800 сек в 3 часах                                                                                      10800:50=216 деталей изготовит токарь за 3 часа работы

Answer 2

Calculating the Number of Parts Produced

To calculate the number of parts a lathe operator can produce in 3 hours, we can use the following steps:

1. Calculate the Total Work Time in Hours: - The given time is 3 hours.

2. Determine the Production Rate: - The lathe operator produces one part in 50 seconds.

3. Convert the Production Rate to Parts per Hour: - There are 3600 seconds in an hour, so the production rate per hour is 3600 / 50 = 72 parts per hour.

4. Calculate the Total Number of Parts Produced: - Multiply the production rate per hour by the total work time in hours.

Let's proceed with the calculation.

Calculation

- Total work time: 3 hours - Production rate: 72 parts per hour

The total number of parts produced in 3 hours is 216 parts.

Conclusion

If the lathe operator works with the same productivity, they will be able to produce 216 parts in 3 hours.
