Charla wants to cover a certain rectangular area of her driveway with a picture using chalk. If she completes 2/3 of the area in 1/2 hour, how long will it take her to complete the entire picture?(1 point) _of an hour
To find the total amount of time it will take Charla to complete the entire picture, we need to first find the amount of time it took her to complete 2/3 of the area.
If 2/3 of the area is completed in 1/2 hour, then 1/3 of the area will be completed in 1/2 hour as well.
Therefore, it will take Charla 1/2 hour to complete 1/3 of the area.
Since 1/3 + 1/3 + 1/3 = 1, it will take her a total of 1/2 + 1/2 + 1/2 = 3/2 of an hour to complete the entire picture.
