You can put this solution on YOUR website!
r*t=d for rate multiplied by time equals distance.\r
\n" ); document.write( "\n" ); document.write( "t=d/r and we have the d cut into \"0.5d%2B0.5d\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First half: \"0.5d%2F20\", hours
\n" ); document.write( "Second half: \"0.5d%2F15\", hours\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The sum of those times must be 3.5 hours.
\n" ); document.write( "\"highlight%280.5d%2F20%2B0.5d%2F15=3.5%29\"
\n" ); document.write( "\"0.5d%281%2F20%2B1%2F15%29=3.5\"
