Answer 1

We can calculate the average unit rate in customers per hour dividing the number of customers the store has in a certain period of time by the number of hours of that period of time.

In this case we have 120 customers in a 6-hour period.

We can then calculate the rate as:

$r=\frac{120\text{ customers}}{6\text{ hours}}=20\text{ customers/hour}$
