It initially travels at a speed of 6 meters per second, and it speeds up at a constant acceleration of 4 meters per second each second. The distance d, in meters, that this object travels is given by the equation d = 2t^2 + 6t, where t is in seconds. According to this

d = 2t^2 + 6t
\n" ); document.write( "---------
\n" ); document.write( "d = 108
\n" ); document.write( "2t^2 + 6t = 108
\n" ); document.write( "t^2 + 3t - 54 = 0
\n" ); document.write( "(t+9)*(t-6) = 0
\n" ); document.write( "t = 6 seconds (ignore the -9 seconds)\r
\n" ); document.write( "\n" ); document.write( "
