Well, we can logic it out...
\n" ); document.write( "If the temperature drops from 70 to 58, it dropped 12 degrees.
\n" ); document.write( "If it took 5 hours, then we divide 12 degress by 5 hours, and get
\n" ); document.write( "12 / 5 = 2.4 degrees per hour
\n" ); document.write( "We can look at it another way too...
\n" ); document.write( "(70 - 58) / (5 - 0) = 2.4
\n" ); document.write( "
\n" );
