Mr. Fox and Mr. Ox are running to the other end of the football field.
\n" ); document.write( " It takes Mr. Ox 2 seconds to run 10 yards
\n" ); document.write( " ad Mr. Fox 5 second to run 10 yards.
\n" ); document.write( " Mr. Fox had a 20 yard head start.
\n" ); document.write( " How long does it take Mr. Ox to catch Mr. Fox?
\n" ); document.write( ":
\n" ); document.write( "Find O's speed: 10/2 = 5 yds/sec
\n" ); document.write( "Find F's speed: 10/5 = 2 yds/sec
\n" ); document.write( ":
\n" ); document.write( "Let t = time for O to catch F (in seconds)
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation; dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "O's dist = F's dist + 20 yds
\n" ); document.write( "5t = 2t + 20
\n" ); document.write( "5t - 2t = 20
\n" ); document.write( "3t = 20
\n" ); document.write( "t = 20/3 sec, about 6.67 seconds
\n" ); document.write( ":
\n" ); document.write( "Check this, how many yards each ran
\n" ); document.write( "6.67 * 5 = 33.3 yds; O's run
\n" ); document.write( "6.67 * 2 = 13.3 yds: F's run
\n" ); document.write( "------------------------
\n" ); document.write( "difference: 20 yds
