Question 873180: 2. One model copier works 3 times as fast as the other. Working together, the copiers can complete a report in 8 min. If the faster copier breaks down, how long will it take the slower copier to do the job?

You can put this solution on YOUR website!
Let +R+ = the rate of the slower copier
+3R+ = the rate of the faster copier
--------------------
Working together, their rate is:
( 1 report ) / ( 8 min ), so
+R+%2B+3R+=+1%2F8+
+4R+=+1%2F8+
+R+=+1%2F32+
The slower copier will take 32 min
to do the job
