The number of square feet that she can paint in one hour will be 31.67 square feet per hour.
The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
Stefanie is painting her bedroom. She can paint 12 and 2/3 square feet in 2/5 of an hour.
The total number of squares is given as,
Area = 12 + 2/3
Area = 38/3 square feet
Then the number of square feet that she can paint in one hour is given as,
Rate = (38/3) / (2/5)
Rate = (38 x 5) / (2 x 3)
Rate = 31.67 square feet per hour
The number of square feet that she can paint in one hour will be 31.67 square feet per hour.

Answer:
31 2/3 .
Step-by-step explanation:
To find how many square feet Stefanie can paint in one hour, divide the number of square feet by the fraction of an hour:
12 2/3 divided by 2/5 = 38/3 divided by 2/5.
=38/3 times 5/2
=190/6
=31 2/3 .
B: x > 7
C: x > 12
D:x < 7
