You can put this solution on YOUR website!
the time t taken to be 150 miles apart is the same, since they start at the same time
\n" ); document.write( "south car 60 mph
\n" ); document.write( "north car = 30 mph\r
\n" ); document.write( "\n" ); document.write( "since they are moving away add up speeds
\n" ); document.write( "=90 mph\r
\n" ); document.write( "\n" ); document.write( "Distance = r*t
\n" ); document.write( "150= 90 t
\n" ); document.write( "
\n" );
