A passenger train going 50 miles per hour meets and passes another passenger train which is traveling in the opposite direction at exactly the same speed. A young woman riding in the train looks out the window, and notes that it takes 5 seconds for the train to pass by hers.
\n" ); document.write( "How long is the other train?
\n" ); document.write( ":
\n" ); document.write( "Relative speed; you can think of this as a train passing a fixed point at 100 mph
\n" ); document.write( ":
\n" ); document.write( "The length of the train would be how far it will travel in 5 sec at 100 mph
\n" ); document.write( ":
\n" ); document.write( "3600 sec in 1 hr
\n" ); document.write( ":
\n" ); document.write( "Length of train: 100 * $\"5%2F3600\"$ = 500/3600 = .139 miles or 733.33 ft\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
