Let $\"+t+\"$ = time in hours
\n" ); document.write( "In dry conditions,
\n" ); document.write( " $\"+d+=+75%2At+\"$ km
\n" ); document.write( " $\"+20+\"$ minutes x $\"+1%2F60+\"$ hours/minutes = $\"+1%2F3+\"$ hr
\n" ); document.write( " $\"+d+=+75%2A%281%2F3%29+\"$
\n" ); document.write( " $\"+d+=+25+\"$ km
\n" ); document.write( "------------
\n" ); document.write( "In wet conditions:
\n" ); document.write( " $\"+d+=+50%2At+\"$
\n" ); document.write( " $\"25+=+50%2At+\"$
\n" ); document.write( " $\"+t+=+1%2F2+\"$ hrs
\n" ); document.write( "It will take him a half hour to reach home\r
