A motor spins 300 revolutions/60 seconds. What is the unit rate?
30 revolutions per minute
60 seconds per 300 revolutions
1 revolution per 300 minutes
300 revolutions per 60 seconds
The unit rate is 30 revolutions per minute.
To find the unit rate, we need to determine the amount of revolutions per time interval. In this case, we have 300 revolutions in 60 seconds.
To convert this to a unit rate, we divide the number of revolutions by the number of seconds.
So the unit rate is 300 revolutions/60 seconds, which simplifies to 5 revolutions/second.
To find the unit rate, we need to determine how many revolutions occur per unit of time. In this case, we are given that the motor spins 300 revolutions in 60 seconds.
To express this as a unit rate, we divide 300 revolutions by 60 seconds:
300 revolutions / 60 seconds = 5 revolutions per second
Therefore, the unit rate is 5 revolutions per second.
