Question

Автомат штампует 2000 деталей каждые 3 минуты.Сколько деталей отштампует этот автомат за 1 час?за 7 часов?

Answer 1

Скорость автомата = 2000/3
за час сделает 2000/3 * 1= 666
за 7 666*7 = 4662

Answer 2

1)1ч=60 мин
2)60:3=20(дет.)
3)2000*20=40000(детали)за 1 час

1)1ч=60 мин
2)7*60=420(часов)
3)40000*7=280000(деталей)

ЭТО ТОЧНО ТАК!!!

Answer 3

Calculating the Number of Stamped Parts

To calculate the number of parts stamped by the machine in 1 hour and 7 hours, we can use the information provided.

The machine stamps 2000 parts every 3 minutes.

Number of parts stamped in 1 hour: To find the number of parts stamped in 1 hour, we can calculate the number of 3-minute intervals in 1 hour and then multiply it by the number of parts stamped in 1 interval.

Number of parts stamped in 7 hours: Similarly, to find the number of parts stamped in 7 hours, we can calculate the number of 3-minute intervals in 7 hours and then multiply it by the number of parts stamped in 1 interval.

Calculation

1. Number of parts stamped in 1 hour: - There are 60 minutes in 1 hour. - 60 minutes / 3 minutes = 20 intervals in 1 hour. - 20 intervals * 2000 parts = 40,000 parts in 1 hour. [[6 #]]

2. Number of parts stamped in 7 hours: - 7 hours * 60 minutes = 420 minutes. - 420 minutes / 3 minutes = 140 intervals in 7 hours. - 140 intervals * 2000 parts = 280,000 parts in 7 hours. [[6 #]]

Therefore, the machine will stamp 40,000 parts in 1 hour and 280,000 parts in 7 hours.
