\n" ); document.write( " If they started at the same point on the track but ran in opposite directions how long would it take for them to meet each other.
\n" ); document.write( ":
\n" ); document.write( "let t = time for them to meet
\n" ); document.write( ":
\n" ); document.write( "Find their speed in meter/sec
\n" ); document.write( "James: 400/55 = 7.27 m/sec
\n" ); document.write( "Henry: 400/62 = 6.45 m/sec
\n" ); document.write( ":
\n" ); document.write( "When they meet the total distance they have run = 400 m
