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? (Hint: Since they are traveling in the same direction, the distance between them will be the difference of their distances.)
You can put this solution on YOUR website! 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.
