Let $\"+d+\"$ = the distance in km it covers in 1 hr
\n" ); document.write( "Speed = $\"+d%2F1+\"$ kmi/hr
\n" ); document.write( " $\"+d+=+r%2At+\"$
\n" ); document.write( " $\"+d+=+%28+d%2F1+%2B+10+%29%2At+\"$
\n" ); document.write( " $\"+t+=+d+%2F+%28+d+%2B+10+%29+\"$ hrs\r
\n" ); document.write( "
