first restaurant second restaurant third restaurant

Explanation:

Step1: Calculate for First Restaurant

To find time per customer, divide total time by number of customers. For first restaurant: $\frac{35}{5} = 7$

Step2: Calculate for Second Restaurant

For second restaurant: $\frac{81}{9} = 9$

Step3: Calculate for Third Restaurant

For third restaurant: $\frac{42}{7} = 6$

Step4: Determine Fastest

Compare the times: 6 (third) < 7 (first) < 9 (second). So third restaurant is fastest.

Answer:

Time taken per customer for the first restaurant: 7 minutes
Time taken per customer for the second restaurant: 9 minutes
Time taken per customer for the third restaurant: 6 minutes
Select the restaurant that served the fastest: Third restaurant
