It is unclear when Roger started painting.
\n" ); document.write( "If they both painted from the beginning and finished it in an hour then we can calculate that Tony can do the job in 7/2 hours and can do 1/3.5 or 2/7 in one hour
\n" ); document.write( "let x be Roger's part
\n" ); document.write( "2/7+x=1
\n" ); document.write( "x=5/7
\n" ); document.write( "so Roger can do 5/7 in one hour
\n" ); document.write( "and can do the whole job in 7/5 hours or 1 2/5 hours or 1 hour and 24 minutes
\n" ); document.write( "The problem is poorly worded.
\n" ); document.write( "Does the question mean that Tony started the job and Roger has to finish it alone or that Roger would be doing the whole job alone?
