find the number of days 4 workers can complete a job if 10 workers can complete the job at in 2 days
4x = 10*2
x = 5 days
or,
2/5 the workers, so 5/2 the time: 5/2 * 2 = 5
To find the number of days 4 workers can complete the job, we can use the concept of "worker-hours."
If 10 workers can complete the job in 2 days, it means that they work together for a total of 10 x 2 = 20 worker-days.
Since the number of worker-days is constant, we can set up a proportion:
(Number of workers) x (Number of days) = Total worker-days
Using the proportion, we can solve for the number of days for 4 workers:
10 x 2 = 4 x (Number of days)
20 = 4 x (Number of days)
Divide both sides of the equation by 4:
20/4 = (Number of days)
5 = (Number of days)
Therefore, 4 workers can complete the job in 5 days.
To find the number of days it takes for 4 workers to complete a job, given that 10 workers can complete the job in 2 days, we can use the concept of "worker-hours."
The concept of worker-hours considers the total amount of work completed by a certain number of workers in a specific time period. It is calculated by multiplying the number of workers by the number of hours worked.
Let's calculate the total worker-hours required to complete the job using 10 workers in 2 days:
Total worker-hours = Number of workers × Number of days
Since 10 workers can complete the job in 2 days, we have:
Total worker-hours = 10 workers × 2 days
Total worker-hours = 20 worker-days
Now, we can find the number of days needed for 4 workers to complete the job. Let's denote this as "x":
Total worker-hours = Number of workers × Number of days
20 worker-days = 4 workers × x days
To solve for "x," we need to isolate it on one side of the equation. Therefore, we can divide both sides of the equation by 4 workers:
20 worker-days ÷ 4 workers = x days
Simplifying the equation gives us:
5 days = x
Therefore, 4 workers can complete the job in 5 days.
8 days for 4 workers to complete a job
4x2=8
