\n" ); document.write( "-----
\n" ); document.write( "Assume the student starts at (0,0)
\n" ); document.write( "7 km north moves him to (0,7)
\n" ); document.write( "5 km west moves him to (-5,7)
\n" ); document.write( "----
\n" ); document.write( "distance from (0,0) to (-5,7) = ?
\n" ); document.write( "-----
\n" ); document.write( "d = sqrt[5^2+7^2] = sqrt[25+49] = sqrt[74] = 8.6 km
