Question

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?

How would I do this problem if the options are the following choices:

A: 12 Square Feet Per Hour

B: 17 1/3 Square Feet Per Hour

C: 18 2/3 Square Feet Per Hour

D: 27 Square Feet Per Hour.

Answer 1

D. 27 square feet per hour

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,

`9*3=27` square feet per hour

This is called finding the unit rate of a scenario.
