A man is three eighths of the way across a train bridge when he hears a train coming from behind.
\n" ); document.write( " If he runs as fast as he can back toward the train, he will get off the bridge just in time to avoid a collision.
\n" ); document.write( " Also, if he runs as fast as possible away from the train, he will get off the bridge (on the other side) just in time to avoid a collision.
\n" ); document.write( " The train is traveling at 60 miles per hour.
\n" ); document.write( " How fast does the man run?
\n" ); document.write( ":
\n" ); document.write( "From the information given, we sum this up with the statement:
\n" ); document.write( " \"The train travels the full length of the bridge while the man run's 2/8 of the length of the bridge\"
\n" ); document.write( ":
\n" ); document.write( "Change 2/8 to .25
\n" ); document.write( ":
\n" ); document.write( "let s = the speed of the man
\n" ); document.write( "A ratio equation
\n" ); document.write( "\"s%2F60\" = \".25%2F1\"
\n" ); document.write( "s = .25*60
\n" ); document.write( "s = 15 mph is the speed of the running man
\n" ); document.write( "
\n" ); document.write( "
\n" );
