To complete 23% of the area in 12 hours, we can set up a proportion:
12 hours is to 23% as X hours is to 100%.
This can be written as:
12/23 = X/100.
To solve for X, we can cross multiply:
23 * X = 12 * 100.
23X = 1200.
Dividing both sides by 23 gives us:
X = 1200/23.
Therefore, it will take Charla approximately 52.17 hours (or about 52 hours and 10 minutes) to complete the entire picture.
