You can put this solution on YOUR website!
How far will your have gone? She left 3/4 of an hour before you and will drive a total of 3/4 + 4 = 19/4 hours.
\n" ); document.write( "At 60mph, she will travel \"Distance+=+Speed+%2A+Time\"
\n" ); document.write( "\"Distance+=+60+%2A+19%2F4\"
\n" ); document.write( "\"Distance+=+285\" miles\r
\n" ); document.write( "\n" ); document.write( "So the total distance is 285.
\n" ); document.write( "How fast do you have to drive to cover 285 miles in just 4 hours?
\n" ); document.write( "\"Distance+=+Speed+%2A+Time\"
\n" ); document.write( "\"285+=+Speed+%2A+4\"
\n" ); document.write( "\"285%2F4+=+Speed\"
\n" ); document.write( "\"71.25\"mph
\n" ); document.write( "Be careful of the speed limits! A few extra minutes is better than a speeding ticket!!
