The 1st train takes 2 hrs to go from A to B
\n" ); document.write( "Let \"+d+\" = distance from A to B
\n" ); document.write( "\"+d+=+90%2A2+\"
\n" ); document.write( "\"+d+=+180+\" Km
\n" ); document.write( "-------------
\n" ); document.write( "The 2nd train takes 1 hr and 20 min which is
\n" ); document.write( "\"+1.333+\" hrs to go the same distance
\n" ); document.write( "\"+180+=+r%2A1.333+\"
\n" ); document.write( "\"+r++=+135+\"
\n" ); document.write( "The average speed of the 2nd train is 135 km/hr
