Question 1159954
.
<pre>

Let "r" be the rate of the slower plane, in miles per hour.

Then the rate of the faster plane is (r+97) mph.


The total distance equation is


    12344 = 8r + 8*(r+97)


Simplify and solve


    r + (r+97) = 12344/8 = 1543

    2r                   = 1543-97 = 1446

     r                             = 1446/2 = 723.


<U>ANSWER</U>.  The rates of the planes are  723 mph  and  723+97 = 820 mph.
</pre>

Solved.
