\n" ); document.write( "Find the time it takes to cover 1 mi at 63 mph speed in seconds
\n" ); document.write( "\"1%2F63\" * 3600 = 57.143 sec
\n" ); document.write( "your relative speed to the train: 63 + 28 = 91 mph
\n" ); document.write( "Find how far you travel (in feet) in 1 sec at 91 mph
\n" ); document.write( "\"%2891%2A5280%29%2F3600\" = 133.467 ft
\n" ); document.write( "Find how many ft in 57.143 sec at this speed
\n" ); document.write( "57.143 * 133.46 = 7626.7 ft is the length of the train
\n" ); document.write( "
