Question 1135801
.


            Ignore post by @josgarithmetic, since it is totally wrong  (giving the answer of  45  mph for the slower car).


            The correct solution is below:



<pre>
Let "r" be the speed of the slower car. Then


    6r + 6*(r+10) = 540     <<<---===  the sum of the two distances


    6r + 6r + 60 = 540

    12r = 540-60

     r =  480/12 = 40.


<U>ANSWER</U>.  The slower car speed is 40 mph;  the faster car speed is 50 mph.
</pre>

Solved.
