The average speed of one airplane is 200 mph faster than that of an automobile. If the automobile starts at 3 a.m. and the airplane starts from the same place at 11 a.m., they will have traveled the same number of miles by 1:00 p.m.
If r represents the rate of the automobile, how many miles does the plane travel?
200r
2(200 + r)
10r
