Answer 1

Answer:

$2,000\ \frac{cm^{2}}{min}$

Step-by-step explanation:

The correct question is

Mia paints interior walls at a rate of 12 m^2/h. At what rate does she paint in cm^2/min?

Remember that

$1\ m=100\ cm$

$1\ h=60\ min$

Convert m^2/h to cm^2/min

substitute the values

$12\ \frac{m^{2}}{h}=12\frac{(100)^{2}}{60}=2,000\ \frac{cm^{2}}{min}$
