You can put this solution on YOUR website!
Let $\"+t+\"$ = time in hrs for trip
\n" ); document.write( " $\"+t+-+4%2A%2821%2F60%29+\"$ = actual time spent driving
\n" ); document.write( " $\"+t+-+21%2F15+\"$
\n" ); document.write( " $\"+t+-+7%2F5+\"$ hrs
\n" ); document.write( " $\"+456+=+75%2A%28t+-+7%2F5%29+\"$
\n" ); document.write( " $\"+456+=+75t+-+7%2A15+\"$
\n" ); document.write( " $\"+75t+=+456+%2B+105+\"$
\n" ); document.write( " $\"+75t+=+561+\"$
\n" ); document.write( " $\"+t+=+7.48+\"$
\n" ); document.write( "You need 7.5 hrs
