~~~~~~~~~~~~~~~~


<pre>
To find the average speed, you should divide the travel distance by the travel time,
in consistent units.


The travel distance is 20 km (given).


The travel time is 24 minutes, or  {{{24/60}}} = {{{2/5}}} of an hour.


THEREFORE, the average speed is


    {{{20/((2/5))}}} = {{{(20*5)/2}}} = 10*5 = 50 kilometers per hour.    <U>ANSWER</U>
