Question

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

Answer 1

12m^2/h》cm^2/min

12m^2/h × 1 h/60 min=.2m^2/min

.2m^2/min × 10000cm^2/1 m^2=2000 cm^2/min

2000cm^2/min

Answer 2

Answer: Mia paints the walls at a rate of $2000 cm^2/min$.

Explanation:

It is given that Mia paints interior walls at a rate of $12m^2/h$.

We know that,

1 m = 100 cm

$1m\times 1m=100cm\times 100cm$

$1m^2=10000cm^2$

We also know that,

1 h = 60 min

$12m^2/h=12\times\frac{10000}{60} cm^2/min$

$12m^2/h=2\times{1000}cm^2/min$

$12m^2/h=2000cm^2/min$

Therefore, we can say that she paints the interior walls at a rate of $2000 cm^2/min$.
