Remember the formula for distance is d=r*t, where d is distance, r is the rate, and t is time.
\n" ); document.write( "Let's plug in the rate of the witch (16 mph) and the time it took her (.5 hours) into this equation to find how far she traveled.
\n" ); document.write( "d = 16*.5
\n" ); document.write( "d = 8
\n" ); document.write( "So we know that the witch traveled 8 miles. Her return trip should be the same distance, so we know that her flight home will be 8 miles while travelling 24 mph. We can plug this into the distance formula again to find the time (t) her trip will take:
\n" ); document.write( "8 = 24 * t
\n" ); document.write( "We divide both sides by 24, and get:
\n" ); document.write( "8/24 = t
\n" ); document.write( "1/3 = t
\n" ); document.write( "So we know that if the witch travels 24 miles per hour home, the journey will take a third of an hour. \n" ); document.write( "

\n" );
