At 9 am, Bill begins walking west at 4 miles per hour.
\n" ); document.write( " At 9:30 am Sam begins walking south from the same starting point at 4 miles per hour.
\n" ); document.write( "How far apart are Bill and Sam at 11 am?
\n" ); document.write( ":
\n" ); document.write( "From the information given, we know that:
\n" ); document.write( " B's walking time = 2 hrs, therefore 2*4 = 8 mi his distance west
\n" ); document.write( " S's walking time = 1.5 hrs, therefore 1.5*4 = 6 mi his distance south
\n" ); document.write( ":
\n" ); document.write( "The distance between them will the the hypotenuse of a right triagle
\n" ); document.write( "with legs of 8 and 6
\n" ); document.write( "d = \"sqrt%288%5E2%2B6%5E2%29\"
\n" ); document.write( "d = 10 mi between them \n" ); document.write( "
