	time (minutes)	number of customers
second restaurant	21	3
third restaurant	40	10

the time it took per customer for each restaurant:

• the time per customer for the first restaurant: ____ minutes
• the time per customer for the second restaurant: ____ minutes
• the time per customer for the third restaurant: ____ minutes

which restaurant that served the food the fastest?
○ first restaurant
○ second restaurant
○ third restaurant

Explanation:

Step1: Calculate time per customer for each restaurant

For First Restaurant: Time = 42 minutes, Customers = 7. Time per customer = $\frac{42}{7}$ = 6 minutes.
For Second Restaurant: Time = 21 minutes, Customers = 3. Time per customer = $\frac{21}{3}$ = 7 minutes.
For Third Restaurant: Time = 40 minutes, Customers = 10. Time per customer = $\frac{40}{10}$ = 4 minutes.

Step2: Compare the time per customer

We have 4 (Third) < 6 (First) < 7 (Second). So the third restaurant has the least time per customer, meaning it served the fastest.

Answer:

Third Restaurant
