A photocopying machine takes 6 minutes to copy a given amount of pages . After 2/3
of the job has been completed, how many more minutes does it take to end the job
If it takes 6 minutes for the entire job, 2/3 of the job is done in 6 minutes * 2/3 = 4 minutes
Therefore, it will take 6 - 4 = 2 more minutes to finish the job.
