Answer:

D. 27 square feet per hour

Step-by-step explanation:

Step 1:

Find the unit rate. Since 18 tiles are per 2/3 of an hour, we can divide 18 by 2 to get 9 tiles layed per third hour.

Step 2:

Multiply the 9 per third of an hour by 3 to find how many are per hour,

[tex]9*3=27[/tex] square feet per hour


This is called finding the unit rate of a scenario.
