A turntable in a shop makes 36 revolutions per minute. How many revolutions does it make per second?
My answer is 216 revolutions per second. Am I right?
Thanks.
1 min = 60 sec
36 / 60 = 6 * 6 / ( 6 * 10 ) =
2 * 3 * 6 / ( 6 * 10 ) =
2 * 3 / 10 =
2 * 3 / ( 2 * 5 )
= 3 / 5 = 0.6 revolutions per second
To determine the number of revolutions the turntable makes per second, we need to convert from revolutions per minute to revolutions per second.
To convert from minutes to seconds, we multiply by 60 since there are 60 seconds in a minute.
Dividing the given 36 revolutions per minute by 60 will give us the number of revolutions per second.
Therefore, the correct calculation is:
36 revolutions per minute * (1 minute / 60 seconds) = 0.6 revolutions per second.
So, the turntable makes 0.6 revolutions per second, not 216 revolutions per second.
