You can put this solution on YOUR website!
d = rt\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10 = 40t\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10/40 = t\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1/4 = t\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "t = 1/4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So it will take you 1/4 of an hour (or 15 minutes) to drive 10 miles at 40 mph.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So in ideal conditions, you would leave at 8:15 - 0:15 = 8:00...but, you may encounter traffic or unplanned events that will slow you down. \r
\n" ); document.write( "\n" ); document.write( "Also, your speed will vary and it will not be 40 mph the entire way.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So I'd say play it safe and double that 15 minute time to 2*15 = 30 minutes\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So you should leave at 8:15 - 0:30 = 7:45 am\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Note: it doesn't hurt to be early. So even leaving before that will work as well. \n" ); document.write( "
\n" );
