You can put this solution on YOUR website!
As long as the units are all compatible, you
\n" ); document.write( "can use $\"d+=+r%2At\"$
\n" ); document.write( "In this case, you have (miles) = (miles/hr)x(hrs)
\n" ); document.write( "Note that hrs cancel on the right side, and you have
\n" ); document.write( "(miles = miles)
\n" ); document.write( "which is OK
\n" ); document.write( " $\"40+=+60%2At\"$
\n" ); document.write( "divide both sides by $\"60\"$
\n" ); document.write( " $\"t+=+40%2F60\"$ hrs
\n" ); document.write( " $\"t+=+2%2F3\"$ hrs
\n" ); document.write( "To convert to minutes,
\n" ); document.write( " $\"2%2F3\"$ hrs * $\"60\"$ min/hr = $\"%282%2F3%29%2A60+=+40\"$ min
\n" ); document.write( " \n" ); document.write( "

\n" );
