Question 1092138
.
<pre>
Your equation for the speed of the slower plane is

5x + 5(x+80) = 3650.

==========================================>

10x + 400 = 3650  ====>  10x = 3650 - 400 = 3250 ====>  x = 325 mph.


<U>Answer</U>. Slower plane speed 325 mph.  Faster plane speed 325+80 = 405 mph.
</pre>

Solved.
