if 15 workers did a job in 8 hours how long would it take 5 workers to do half this job?
If 15 workers did the job in 8 hours, we can use the formula:
(Number of workers_1 * Time_1) = (Number of workers_2 * Time_2)
To find out how long it would take 5 workers to do the job, we can substitute the values:
(15 * 8) = (5 * Time_2)
Simplifying the equation:
120 = 5 * Time_2
Dividing both sides of the equation by 5:
Time_2 = 120 / 5
Time_2 = 24
Therefore, it would take 5 workers 24 hours to do half the job.
