Caitlin is painting hey bedroom . She paints 42 square in 2/3 hour. At this rate , how many square feet can she paint in 1 hour
To find out how many square feet Caitlin can paint in 1 hour, we will calculate her painting rate.
Caitlin paints 42 square feet in 2/3 hour.
To find her painting rate per hour, we need to divide the number of square feet painted by the time taken:
42 square feet ÷ (2/3 hour) = 42 square feet ÷ (2/3) hour
We can simplify 2/3 as a decimal by dividing 2 by 3:
2 ÷ 3 = 0.67 (rounded to two decimal places)
Let's substitute this decimal into the equation:
42 square feet ÷ 0.67 hour ≈ 62.69 square feet per hour
Therefore, Caitlin can paint approximately 62.69 square feet in 1 hour.
To find out how many square feet Caitlin can paint in 1 hour, we need to divide the given amount of square feet painted in 2/3 hour by the amount of time it took to paint it.
Let's first calculate the amount of square feet Caitlin can paint in 2/3 hour:
42 square feet / 2/3 hour = 42 square feet * 3/2 hour
To simplify, we can multiply the numerator and denominator by 3:
42 square feet * 3/2 hour = (42 * 3) square feet / (2) hour
= 126 square feet / 2 hour
Now we can divide the amount of square feet by the amount of time taken to find the rate per hour:
126 square feet / 2 hour = 63 square feet / 1 hour
Therefore, Caitlin can paint 63 square feet in 1 hour.
To find out how many square feet Caitlin can paint in 1 hour, we need to calculate her painting rate per hour.
Given that Caitlin paints 42 square feet in 2/3 hour, we can set up a proportion to find her painting rate per hour.
Let's call her painting rate per hour "R".
We have the following proportion:
42 square feet / (2/3 hour) = R square feet / 1 hour
To solve for R, we can cross multiply:
42 square feet * 1 hour = (2/3 hour) * R square feet
42 square feet * 1 hour = 2R square feet
Dividing both sides of the equation by 2:
21 square feet * 1 hour = R square feet
Therefore, Caitlin can paint 21 square feet in 1 hour.
