Let $\"+d+\"$ = the distance Bala is behind
\n" ); document.write( "when Ahmad crosses the line
\n" ); document.write( "----------------------------
\n" ); document.write( "When Ahmad crosses the finish line, Bala is
\n" ); document.write( "going to cross in $\"+245+-+235+=+10+\"$ sec
\n" ); document.write( "-------------------------------------
\n" ); document.write( "Bala's speed is:
\n" ); document.write( " $\"+800+%2F+245+=+160+%2F+49+\"$ m/.sec
\n" ); document.write( " $\"+d+=+%28+160%2F49+%29%2A10+\"$
\n" ); document.write( " $\"+d+=+1600%2F49+\"$
\n" ); document.write( " $\"+d+=+32.653+\"$
\n" ); document.write( "Bala is 32.653 m from the finish line
\n" ); document.write( "when Ahmad crosses
\n" ); document.write( "---------------------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+800+-+32.653+=+767.347+\"$
\n" ); document.write( "Bala covers this distance in $\"+235+\"$ sec
\n" ); document.write( " $\"+767.347+%2F+235+=+3.265+\"$ m/sec
\n" ); document.write( "-------------------------------
\n" ); document.write( "Now I can say:
\n" ); document.write( " $\"+3.265+=+800%2F245+\"$
\n" ); document.write( " $\"+3.265+=+3.265+\"$
\n" ); document.write( "Seems to check OK -hope I got it\r
