What would the unit rates be for a store that had 30 customers in 12 minutes?
30/12 = 2.5 customer per minute
To calculate the unit rate for a store that had 30 customers in 12 minutes, you need to divide the number of customers by the time period.
Unit rate = Number of customers / Time period
In this case, the number of customers is 30, and the time period is 12 minutes.
So, the unit rate would be:
Unit rate = 30 customers / 12 minutes
To simplify this, divide both the numerator and denominator by their greatest common factor, which is 6:
Unit rate = 5 customers / 2 minutes
Therefore, the unit rate for the store would be 5 customers per 2 minutes.
