Question 1044860
.
Two vehicles {{{highlight(cross(travelled))}}} traveled (x + 4) kilometers. The first vehicle traveled for (x^2 – 16) hours 
while the second traveled for (2/x-4). Find the speed.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Do you know this formula:  Speed = {{{Distanse/Time}}} ?


Apply it twice.


For the first  body: speed = {{{(x+4)/(x^2-16)}}} = {{{1/(x-4)}}} {{{km/h}}}.

For the second body: speed = {{{(x+4)/((2/(x-4)))}}} = {{{(x^2-16)/2}}} {{{km/h}}}.
