Q. Mia paints interior walls at a rate of 12hm2.At what rate does Mia paint in mincm2 ?
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.1 meter =100 centimeters1 hour =60 minutes
Convert to Square Centimeters: First, convert square meters to square centimeters. Since 1 meter is 100 centimeters, 1 square meter is 100 cm ∗100 cm = 10,000 square centimeters.
Multiply by Conversion Factor: Now, multiply Mia's rate by the conversion factor to get the rate in square centimeters per hour. 12(m2/h)×10,000(cm2/m2)=120,000(cm2/h)
Convert to Square Centimeters per Hour: Next, convert the rate from per hour to per minute. Since 1 hour is 60 minutes, we divide the rate by 60.120,000(cm2/h)/60(min/h)=2,000(cm2/min)
Convert to Square Centimeters per Minute: Mia's painting rate is therefore 2,000 square centimeters per minute.
