Hi there,
\n" ); document.write( "480 miles in 12 hours
\n" ); document.write( "Speed = Distance/Time
\n" ); document.write( "Speed = 480/12
\n" ); document.write( "Speed = 40mph
\n" ); document.write( "If she increases her speed by 20mph
\n" ); document.write( "she will be travelling at 60mph
\n" ); document.write( "Time = Distance/Speed
\n" ); document.write( "Time = 300/60
\n" ); document.write( "Time = 5 hours.
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
