Let \"+s+\" = the woman's speed in km/hr
\n" ); document.write( "Let hrs
\n" ); document.write( "---------------------
\n" ); document.write( "\"+d+=+4%2A%281%2F4%29+\"
\n" ); document.write( "\"+d+=+1+\" km
\n" ); document.write( "----------------
\n" ); document.write( "Convert meters to km
\n" ); document.write( "\"+125%2F1000+=+1%2F8+\" km
\n" ); document.write( "-----------------------
\n" ); document.write( "The woman's equation is:
\n" ); document.write( "\"+1+-+1%2F8+=+s%2A%28+1%2F4+%29+\"
\n" ); document.write( "\"+7%2F8+=+s%2A%28+1%2F4+%29+\"
\n" ); document.write( "Multiply both sides by \"+4+\"
\n" ); document.write( "\"+s+=+7%2F2+\"
\n" ); document.write( "\"+s+=+3.5+\"
\n" ); document.write( "The woman's speed is 3.5 km/hr
\n" ); document.write( "-------------------------------
\n" ); document.write( "check:
\n" ); document.write( "At her rate, in 1/4 hr, she travels \"+%28+7%2F2+%29%2F4+=+7%2F8+\" km
\n" ); document.write( "\"+1+-+7%2F8+=+1%2F8+\" km which was her head start
\n" ); document.write( "OK \r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
