Question 1145633
.
<pre>

Let  "d"  be the walking distance, in kilometers (the same as jogging distance (!) ).


Then the time walking is  {{{d/6}}} hours, while the time jogging is  {{{d/12}}} hours.


Total time is 2 hours


    {{{d/6}}} + {{{d/12}}} = 2   hours.


It is your basic equation.  (Also called "time" equation)

At this point, the setup is completed.

To solve the equation, multiply both sides by 12


    2d + d = 2*12

    3d     = 24

     d     = 24/3 = 8 kilometers.


Distance walking = distance jogging = 8 kilometers.


The course is  8 + 8 = 16 kilometers long.    <U>ANSWER</U>
