It takes 4 workers working at equal rates to finish a job in 48 days. How long will 3 workers take to finish the same job?

By the inverse proportionality method between workers and days, the product of workers and days remains constant. We set up the equation 4 workers multiplied by 48 days equals 3 workers multiplied by the unknown number of days. Solving this gives 192 equals 3 times the days, so the days equal 64. It will take 3 workers 64 days to finish the job.
