12(m^(2))/((h)).
At what rate does Mia paint in 
(cm^(2))/(min) ?

Mia paints interior walls at a rate of 12m2 h 12 \frac{\mathrm{m}^{2}}{\mathrm{~h}} .\newlineAt what rate does Mia paint in cm2min \frac{\mathrm{cm}^{2}}{\min } ?

Full solution

Q. Mia paints interior walls at a rate of 12m2 h 12 \frac{\mathrm{m}^{2}}{\mathrm{~h}} .\newlineAt what rate does Mia paint in cm2min \frac{\mathrm{cm}^{2}}{\min } ?
  1. Conversion Factors: To convert Mia's painting rate from square meters per hour to square centimeters per minute, we need to know the conversion factors between meters and centimeters, and between hours and minutes.\newline11 meter =100= 100 centimeters\newline11 hour =60= 60 minutes
  2. Convert to Square Centimeters: First, convert square meters to square centimeters. Since 11 meter is 100100 centimeters, 11 square meter is 100100 cm * 100100 cm = 10,00010,000 square centimeters.
  3. Multiply by Conversion Factor: Now, multiply Mia's rate by the conversion factor to get the rate in square centimeters per hour. \newline12(m2/h)×10,000(cm2/m2)=120,000(cm2/h)12 (m^2/h) \times 10,000 (cm^2/m^2) = 120,000 (cm^2/h)
  4. Convert to Square Centimeters per Hour: Next, convert the rate from per hour to per minute. Since 11 hour is 6060 minutes, we divide the rate by 6060.\newline120,000(cm2/h)/60(min/h)=2,000(cm2/min)120,000 (\text{cm}^2/\text{h}) / 60 (\text{min}/\text{h}) = 2,000 (\text{cm}^2/\text{min})
  5. Convert to Square Centimeters per Minute: Mia's painting rate is therefore 2,0002,000 square centimeters per minute.
