A bottleneck due to an accident on a highway produces two lines of cars each having a length of 720 m. If the average distance between cars is 2.5m and the average length of a car is 3.5m , how many cars are there?\r
\n" ); document.write( "\n" ); document.write( "A 120 B 122 C 240 D 242\r
\n" ); document.write( "\n" ); document.write( "The length of car + gap = 6m\r
\n" ); document.write( "\n" ); document.write( "Total length of of the line = 720 m\r
\n" ); document.write( "\n" ); document.write( "720/6 = 120 cars in 1 line\r
\n" ); document.write( "\n" ); document.write( "so there will be 240 cars in both the lines.
\n" ); document.write( "
\n" );
