\n" ); document.write( "\"it takes 10 seconds for an elevator to go from the first floor to the fifth\"
\n" ); document.write( "therefore
\n" ); document.write( "40 ft in 10 sec; that's 4 ft/sec
\n" ); document.write( ":

\n" ); document.write( "17 - 5 = 12 floors
\n" ); document.write( "that's
\n" ); document.write( "10 * 12 = 120 ft
\n" ); document.write( "then
\n" ); document.write( "120/4 = 30 seconds \n" ); document.write( "
