Add up all the walks heading east:
\n" ); document.write( " $\"+10+\"$ km
\n" ); document.write( " $\"+12+\"$ km
\n" ); document.write( " $\"+11+\"$ km
\n" ); document.write( " $\"+10+%2B+12+%2B+11++=+33+\"$ km
\n" ); document.write( "----------------------------
\n" ); document.write( "Add up all the walks heading north
\n" ); document.write( " $\"+5+\"$ km
\n" ); document.write( " $\"+3+\"$ km
\n" ); document.write( " $\"+2+\"$ km
\n" ); document.write( " $\"+5+%2B+3+%2B+2+=+10+\"$ km
\n" ); document.write( "----------------------
\n" ); document.write( "Use the pythagorean theorem
\n" ); document.write( "to find the straight line distance:
\n" ); document.write( " $\"+d%5E2+=+33%5E2+%2B+10%5E2+\"$
\n" ); document.write( " $\"+d%5E2+-+1089+%2B+100+\"$

\n" ); document.write( " $\"+d+=+34.48+\"$
\n" ); document.write( "It is 34.48 km to grandma's house
\n" ); document.write( "Hope I got it\r
