Question

Вентилятор делает 2400 оборотов в минуту сколько оборотов он сделает за 8 секунд

Answer 1

1 минута = 60 сек ⇒ 2 400 оборотов в 60 сек.
Узнаем обороты в одну секунду:
2 400:60= 40 (оборотов)

И узнаём обороты за 8 секунд:
40×8= 320 (оборотов)

Answer 2

19200 оборотов в минуту........................

Answer 3

To find out how many revolutions the fan makes in 8 seconds, we can use the given information that the fan makes 2400 revolutions per minute.

First, we need to convert the minutes to seconds, as the fan's speed is given in revolutions per minute. There are 60 seconds in 1 minute, so:

2400 revolutions per minute = 2400 revolutions / 60 seconds = 40 revolutions per second

Now that we know the fan makes 40 revolutions per second, we can find out how many revolutions it makes in 8 seconds:

Number of revolutions in 8 seconds = 40 revolutions/second * 8 seconds = 320 revolutions

Therefore, the fan will make 320 revolutions in 8 seconds.
