west 10 miles, south 5 miles, west 30 miles, and north 35 miles=west 40 miles, north 30
\n" ); document.write( "(30)2+(40)2=n2
\n" ); document.write( "900+1600=n2
\n" ); document.write( "2500=n2
\n" ); document.write( "n=50 or -50
\n" ); document.write( "Throwing out the negative answer, we get the distance to be 50 miles directly.. \n" ); document.write( "
