By the time firework a has been launched, firework b has already been launched for 0.25 seconds, so if we treat the two as equations, then
\n" ); document.write( "\"a=220%28t%29\"
\n" ); document.write( "\"b=200%28t%29%2B200%280.25%29\"
\n" ); document.write( "And we want to know when these two equal eachother, as that's they will both detonate.
\n" ); document.write( "\"220t=200t%2B200%280.25%29\"
\n" ); document.write( "\"20t=50\"
\n" ); document.write( "\"t=2.5\"
\n" ); document.write( "
\n" );
