Question 1051050
Two planes just took off from Milwaukee, WI.  
The first plane is traveling 2 times as fast as the second plane.  After traveling in the same direction for 9 hours, they are 990 miles apart.  What is the average speed of each plane?
---------------
990/9 = 110 mi/hr difference in speed.
--> r1 = r2 + 110
======================
r1 = 2*r2 (stated)
---
2r2 = r2 + 110
r2 = 110 mi/hr
r1 = 220 mi/hr
===================
Planes that slow don't have 9 hours of fuel, and I doubt they refuel in the air.
