:
I think there are an infinite number of solutions to this problem
:
Let s = speed of the slower plane
Then
(s+100) = speed of the faster plane
:
Since they going in opposite direction their relative speed = 2s+100
:
Time = dist/(2s+100)
:
Graph this (y=time; x=speed of the slower plane):
a couple of integer examples
x = 150 mph, y = 5 hrs
x = 200 mph, y = 4 hrs
x = 450 mph, y = 2 hrs
