Suppose I can mow the lawn at the park by my house in 8 hours.
\n" ); document.write( " It takes my neighbor 10 hours to mow he same lawn.
\n" ); document.write( "If I started mowing at 8am, then he came and began helping me at 10am, what time would we finish mowing the lawn?
\n" ); document.write( ":
\n" ); document.write( "Let t = your mowing time
\n" ); document.write( "then
\n" ); document.write( "(t-2) = neighbor's mowing time
\n" ); document.write( ":
\n" ); document.write( "Let the completed job = 1
\n" ); document.write( ":
\n" ); document.write( "\"t%2F8\" + \"%28t-2%29%2F10\" = 1
\n" ); document.write( "multiply by 40 to clear the denominators, results:
\n" ); document.write( "5t + 4(t-2) = 40
\n" ); document.write( "5t + 4t - 8 = 40
\n" ); document.write( "9t = 40 + 8
\n" ); document.write( "9t = 48
\n" ); document.write( "t = 48/9
\n" ); document.write( "t = 5\"1%2F3\" hrs or 5 hrs 20 min, working together
\n" ); document.write( "You would finish at: 8:00 + 5:20 = 1:20 PM
