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 find the answer, we need to find the portion of the picture that Charla can complete in 1 hour. We can do this by dividing the area of the picture by the time it takes her to complete that area.
If Charla completes 23 of the area in 12 hours, then she completes 1/12 of the area in 1 hour.
Therefore, it will take her 12 hours to complete the entire picture.
To find out how long it will take Charla to complete the entire picture, you need to calculate the rate at which she completes the area.
Let's assume that the rectangular area of her driveway is A, and the amount she completes in 12 hours is 23% of the area.
So, the rate at which she completes the area is 23% per 12 hours.
To find out the time it will take her to complete the entire picture, you can set up a proportion:
23% / 12 hours = 100% / x hours
Cross-multiplying:
23% * x hours = 100% * 12 hours
0.23 * x hours = 12 hours
Dividing both sides by 0.23:
x hours = 12 hours / 0.23
x hours ≈ 52.17 hours
Therefore, it will take Charla approximately 52.17 hours to complete the entire picture.
To find out how long it will take Charla to complete the entire picture, we need to determine the proportion of the picture she can complete per hour.
We know that she can complete 23% (or 0.23) of the area in 12 hours. So, the fraction of the picture she completes per hour is 0.23/12.
To find out how long it will take her to complete the entire picture, we can use the formula:
Time = 1 / (fraction completed per hour)
Plugging in the values, we get:
Time = 1 / (0.23/12)
Time = 12 / 0.23
Time ≈ 52.17 hours
So, it will take Charla approximately 52.17 hours to complete the entire picture.
