Question 192300: Two airplanes left the same airport traveling in opposite directions. If one airplane averages 400 miles per hour and the other airplane averages 250 miles per hour,in how many hours will the distance between the two planes be 1625 miles?

Suppose that in x hours the distance between the two planes will be 1625 miles.
In x hours, the distance traveled by each plane is:
Plane 1: 400x
Plane 2: 250x
The total distance covered is 400x + 250x.
Setting it equal to 1625, we have
400x + 250x = 1625
Solving for x, we have
650x = 1625
x= 2.5 hours
