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)
[answer]
of an hour
To complete 2/3 of the area in 1/2 hour, it means that she completes 1/3 of the area in 1/2 hour.
Therefore, it will take her 2 times as long to complete the entire picture.
Hence, it will take her 1/2 hour x 2 = 1 hour to complete the entire picture.
Therefore, the answer is 1 hour.
wrong
I apologize for the incorrect response.
To find out the total time it will take to complete the entire picture, we can set up a proportion.
Since Charla completed 2/3 of the area in 1/2 hour, we can set up the following ratio:
2/3 area / 1/2 hour = 1 (whole area) / x (total time)
To find x, we can cross multiply:
(2/3) * x = (1/2) * 1
Multiplying both sides by 3/2 to isolate x:
x = (1/2) * (3/2)
x = 3/4
Therefore, it will take her 3/4 of an hour (or 45 minutes) to complete the entire picture.
To find out how long it will take Charla to complete the entire picture, we can use the information given.
Let's assume the rectangular area of her driveway is divided into 6 equal parts. Charla completes 2 parts (2/6) of the area in 1/2 hour.
First, we need to find out how many parts are left to complete. Since she already completed 2 parts, there are 4 parts remaining (6 - 2 = 4).
Now, we need to find out how long it takes Charla to complete 1 part of the area. Since she completed 2 parts in 1/2 hour, it means she completes 1 part in 1/4 hour (1/2 รท 2 = 1/4).
Finally, to find out how long it will take her to complete the entire picture, we multiply the time to complete 1 part by the number of parts remaining.
(1/4 hour) x (4 parts) = 1 hour.
Therefore, it will take Charla 1 hour to complete the entire picture.
