John takes 2 hours longer than Andrew to peel 600 pounds of apples. If together they can peel 600 pounds of apples in 8 hours, then how long would it take John to peel the apples working alone?
\n" ); document.write( "------
\n" ); document.write( "Andrew DATA:: time = x hrs/job ; rate = 1/x job/hr
\n" ); document.write( "John DATA: time = x+2 hrs/job ; rate = 1/(x+2) job/hr
\n" ); document.write( "------------
\n" ); document.write( "Together DATA:: time = 8 hrs/job ; rate = 1/8 job/hr
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/x + 1/(x+2) = 1/8
\n" ); document.write( "-----
\n" ); document.write( "8(x+2) + 8x = x(x+2)
\n" ); document.write( "16x + 16 = x^2 + 2x
\n" ); document.write( "----
\n" ); document.write( "x^2 - 14x - 16 = 0
\n" ); document.write( "----
\n" ); document.write( "x = 15.06 hrs (time for Andrew alone)
\n" ); document.write( "x+2 = 17.06 hrs (time for John alone)
