\n" ); document.write( "Let x = time (hours) it takes for both
\n" ); document.write( "then
\n" ); document.write( "x(1/5 + 1/3) = 1
\n" ); document.write( "multiplying both sides by 15:
\n" ); document.write( "x(3 + 5) = 15
\n" ); document.write( "x(8)=15
\n" ); document.write( "x = 1.875 hours
\n" ); document.write( "or
\n" ); document.write( "x = 1 hour and 53 minutes\r
