2800=4u+(u-50)4\r
\n" ); document.write( "\n" ); document.write( "3000=4u+4u
\n" ); document.write( "u=3000/8=375\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so the speed of the first car is 375
\n" ); document.write( "and the other cars speed is 325\r
\n" ); document.write( "\n" ); document.write( "check
\n" ); document.write( "375t+325t=2800
\n" ); document.write( "700t=2800
\n" ); document.write( "t=4
\n" ); document.write( "
