John can finish a work in 8days and peter can finish that same work in 6days.
\n" ); document.write( "They worked together for 2days and peter left.
\n" ); document.write( "How long will it take John to finish the work himself?
\n" ); document.write( ":
\n" ); document.write( "let t = time for John to finish the job
\n" ); document.write( "let the completed job = 1
\n" ); document.write( ":
\n" ); document.write( "Peter works 2 days
\n" ); document.write( "John works (t+2) days
\n" ); document.write( ":
\n" ); document.write( "A shared work equation, each does a fraction of the job, the two fractions add up to 1
\n" ); document.write( "\"%28%28t%2B2%29%29%2F8\" + \"2%2F6\" = 1
\n" ); document.write( "multiply equation by least common multiple, 24; cancel the denominators
\n" ); document.write( "3(t+2) + 4(2) = 24
\n" ); document.write( "3t + 6 + 8 = 24
\n" ); document.write( "3t = 24 - 14
\n" ); document.write( "t = 10/3
\n" ); document.write( "t = 3.33 additional hrs for John to finish the job (3 hrs 20 min)
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this (John work a total of 5.33 hrs)
\n" ); document.write( "\"5.33%2F8%7D%7D+%2B+%7B%7B%7B2%2F6\" =
\n" ); document.write( ".667 + 333 = 1.0
