Freight train 40 mph
\n" ); document.write( "passenger train 60 mph
\n" ); document.write( "
\n" ); document.write( "Freight train 04:00
\n" ); document.write( "passenger train 08:00
\n" ); document.write( "
\n" ); document.write( "Difference in time= 04:00
\n" ); document.write( "Freight train will have covered 160 miles before passenger train starts
\n" ); document.write( "
\n" ); document.write( "catch up distance= 160 miles
\n" ); document.write( "catch up speed = 60 -40 mph
\n" ); document.write( "catch up speed = 20 mph
\n" ); document.write( "
\n" ); document.write( "Catchup time = catchup distance/catch up speed
\n" ); document.write( "catch up time= 160 / 20
\n" ); document.write( "catch up time= 8 hours \r
