Charla wants to cover a 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)Responses
1/3 of an hour
1/2 of an hour
3/4 of an hour
1 hour
To cover 2/3 of the area in 1/2 hour, it means that Charla completes 2/3 * 1/2 = 1/3 of the area in 1/2 hour.
To complete the entire picture, she needs to cover the remaining 1 - 1/3 = 2/3 of the area.
If Charla completes 1/3 of the area in 1/2 hour, then it will take her 2/3 * 1/2 = 1/3 of an hour to complete the remaining area.
Therefore, it will take Charla 1/2 hour + 1/3 of an hour = 5/6 of an hour to complete the entire picture.
So, the answer is 5/6 of an hour, which is closest to 3/4 of an hour.
