A carpenter lays 18 square feet of tiles in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?
1 answer:
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,
square feet per hour
This is called finding the unit rate of a scenario.
