Together Leonard and Donte can do a job in 4 hours and 16 minutes.
\n" ); document.write( " If it takes Leonard 8 hours to do the job alone how long would it take Donte to do the job alone ?
\n" ); document.write( ":
\n" ); document.write( "Let d = time required by D to do the job alone
\n" ); document.write( "Let the completed job = 1
\n" ); document.write( ":
\n" ); document.write( "Do the problem in minutes
\n" ); document.write( "4 hr 16 min = 256 min
\n" ); document.write( "8 hrs = 480 min
\n" ); document.write( ":
\n" ); document.write( "\"256%2F480\" + \"256%2Fd\" = 1
\n" ); document.write( "multiply by 480d
\n" ); document.write( "480d*\"256%2F480\" + 480d*\"256%2Fd\" = 480d
\n" ); document.write( "Cancel the denominators
\n" ); document.write( "256d + 480(256) = 480d
\n" ); document.write( "122880 = 480d - 256d
\n" ); document.write( "122880 = 224d
\n" ); document.write( "d = \"122880%2F224\"
\n" ); document.write( "d = 548.57 minutes converts to 9 hrs 8.57 min\r
