Hi there,
\n" ); document.write( "600 feet = 0.113636 miles
\n" ); document.write( "Total distance to clear
\n" ); document.write( "= 1.113636
\n" ); document.write( "Speed = 200mph
\n" ); document.write( "Time = Distance/Speed
\n" ); document.write( "Time = 1.113636/200
\n" ); document.write( "Time = 20 seconds
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
