Question 800881: Under pressure to make a deadline, an office manager directs her fastest typist to type a document that should take 40 mins. After 15 mins, she realizes the typist won't make the deadline and she asks a second, slower typist to start typing some of the pages. Fifteen minutes later the document is finished. How long would it have taken the slower typist to type the document?

You can put this solution on YOUR website! Under pressure to make a deadline, an office manager directs her fastest typist to type a document that should take 40 mins. After 15 mins, she realizes the typist won't make the deadline and she asks a second, slower typist to start typing some of the pages. Fifteen minutes later the document is finished. How long would it have taken the slower typist to type the document?
-------
1st typist does 15/40 = 3/8 of the job.
------
2nd typist DATA:
time = 15 min for 5/8 job
------
Let rate be "x"
job/rate = time
-----
(5/8)/x = 15 min
x = (5/8)/15
x = 1/24 job/min
=====
2nd typist time 24 min/job
