\n" ); document.write( "(faster acceleration)/(slower acceleration) = (slower time)/(faster time)
\n" ); document.write( "4/3 = x/9
\n" ); document.write( "4*9 = 3*x
\n" ); document.write( "36 = 3x
\n" ); document.write( "3x = 36
\n" ); document.write( "x = 36/3
\n" ); document.write( "x = 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 12 seconds
\n" ); document.write( "
