To find out how long it will take Charla to complete the entire image, we need to find the total amount of time it takes her to complete 2/3 of the area and then calculate how much time it would take to complete the remaining 1/3 of the area.
Given that Charla completes 2/3 of the area in 1/2 hours, we can find the time it takes to complete 1/3 of the area by dividing the time in half: 1/2 / 2 = 1/4 hours.
Therefore, it would take Charla a total of 1/2 + 1/4 = 3/4 hours to complete the entire image on her driveway.
To find out how long it will take Charla to complete the entire image, we need to solve the problem step-by-step.
Step 1: Determine the fraction of area completed per hour.
Since Charla completed 2/3 of the area in 1/2 hours, the fraction of area completed per hour is:
(2/3) / (1/2) = (2/3) * (2/1) = 4/3.
Step 2: Determine the fraction of area remaining.
The fraction of area remaining is 1 - 2/3 = 1/3.
Step 3: Determine the number of hours needed to complete the remaining 1/3 of the area.
Since Charla completes 4/3 of the area per hour, she will need (1/3) / (4/3) = (1/3) * (3/4) = 1/4 hours to complete the remaining area.
Therefore, it will take Charla 1/4 hours (or 15 minutes) to complete the entire image.
To find out how long it will take Charla to complete the entire image, we need to first calculate the time taken to complete 2/3 of the area.
Let's break down the problem:
- 2/3 of the area is completed in 1/2 hour.
- So, if Charla completes 2/3 of the area in 1/2 hour, it means she completes 1/3 of the area in 1/2 hour as well. This is because if 2/3 is completed in 1/2 hour, the remaining 1/3 must also take the same amount of time.
Now, we can calculate the time it takes to complete the entire image:
- If 1/3 of the area is completed in 1/2 hour, it means that the remaining 2/3 will also take the same amount of time.
- So, to find the time taken for the remaining 2/3, we multiply the time taken for 1/3 by 2.
- Therefore, the time taken to complete the entire image is 1/2 hour multiplied by 2, which equals 1 hour.
So, it will take Charla 1 hour to complete the entire image of the spider on her driveway.
