Question 1197002
Not too sure what values you are showing in description:
-----------------------------------------------------------------------------------
Two planes just took off from Milwaukee, WI. The first plane is traveling 2
2
times as fast as the second plane. After traveling in the same direction for 9
9
hours, they are 882
882
miles apart. What is the average speed of each plane?

Maybe your given exercise is this:

So many exercise problems like this one have already been solved on the site.
Do the two planes begin travel at the same time?  Likely they did and this was omitted in the description.


speed of plane1, 2r
speed of plane2, r


{{{SPEED*TIME=DISTANCE}}}


{{{(2r-r)*9=882}}}
You know what to do from here.
