length of 1 train = 300 mtrs.
\n" ); document.write( "length of other train = 200 mtrs.
\n" ); document.write( "..
\n" ); document.write( "speed = 40 kmph
\n" ); document.write( "since they are travelling in opposite directions the effective speed will be 80 kmph.
\n" ); document.write( "1km/hr. = 5/18 mtrs/secnd
\n" ); document.write( "80 km/hr = 5/18* 80 = 22.22 mtrs/second
\n" ); document.write( "..
\n" ); document.write( "The total length of two trains is the distance they have to travel.
\n" ); document.write( "= 500 meters.
\n" ); document.write( " $\"Time+=+distance+%2F+speed\"$
\n" ); document.write( " $\"500%2F22.22\"$
\n" ); document.write( "= 22.5 seconds \n" ); document.write( "

\n" );
