Charla wants to cover a certain rectangular area of her driveway with a picture using chalk. If she completes 23 of the area in 12 hour, how long will it take her to complete the entire picture?(1 point)
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.
To find out how long it will take Charla to complete the entire picture, we need to calculate the time it takes for her to cover 1% of the area.
The given information is that Charla completes 23% of the area in 12 hours.
To find the time it takes to cover 1%, we can divide 12 hours by 23:
12 hours รท 23 = 0.52 hours
Therefore, it will take Charla approximately 0.52 hours to cover 1% of the area.
To determine how long it will take Charla to complete the entire picture, we need to first calculate the amount of area she can cover in one hour. We can find this by dividing the completed area (23) by the time it took her to complete it (12 hours).
Area covered in one hour = Completed area / Time taken
= 23 / 12
= 1.92
Now that we know the rate at which Charla can cover the area, we can calculate the total time it will take her to complete the entire picture. Since she needs to cover the entire rectangular area, we divide the total area by the rate at which she can cover it.
Total time = Total area / Area covered in one hour
However, we do not have the measurements of the area or any other details, so we cannot calculate the total time accurately.
