Hour 1:                       300         -           450
Hour 2:            600                    -                              900
Hour 3:  900                              -                                              1350
1350 + 900 = 2250

Using Linear Equations :)

Let x = be the number of hours the two planes will be 2250 kilometers apart.
300x + 450x = 2250
Simplify
750x = 2250
Divide both sides by 750
750x / 750 = 2250 / 750
x = 3

So they will be 2250km apart in 3 hours.

I take a more heuristic approach.
It's coooooooooooool :D
