\n" ); document.write( "The solution from tutor @josgarithmetic has the typing speed increased BY 60 words per minute; the statement of the problem says the typing speed increased TO 60 words per minute.

\n" ); document.write( "The job was done in 3 hours; at a typing speed of 60 wpm it would have been completed 2 hours faster -- i.e., in 1 hour.

\n" ); document.write( "The time required to complete the job is 1/3 of what it was; that means the typing speed was 3 times what it was before.

\n" ); document.write( "If 60 wpm is 3 times the original speed, then the original typing speed was 20 wpm.

\n" ); document.write( "ANSWER: 20 words per minute
