Coming from opposite directions, a freight train and a passenger train pass each other on parallel tracks.
\n" ); document.write( " The passenger train travels at 60 mph. The freight train travels at 30 mph.
\n" ); document.write( " A passenger observes that it takes 6 seconds to pass the freight train.
\n" ); document.write( " How many feet long is the freight train?
\n" ); document.write( ":
\n" ); document.write( "Since they are going towards each other the speeds are additive: 60+30 = 90 mph
\n" ); document.write( "What is the distance (in feet) traveled in 6 sec at 90 mph
\n" ); document.write( ":
\n" ); document.write( " $\"%2890%2A5280%29%2F3600\"$ * 6 = 792 ft is the length of the freight \n" ); document.write( "

\n" );
