Okay, you are talking about two points in time: 1PM and 3PM. This implies that the beginning point is the same. This means that the final points will indicate a triangular shape. Since the directions are north and west, these are perpendicular directions, meaning the triangle formed would be a right triangle.



The first plane traveling north will be able to travel 300 miles and the second plane will be able to travel 400 miles.



(2 hours x 150 miles per hour = 300 miles)

(2 hours x 200 miles per hour = 400 miles)



So, this means that these are the two legs of the right triangle.



using the pythagorean theorem,



a^2 + b^2 = c^2

300^2 + 400^2 = c^2

90000 + 160000 = c^2

250000 = c^2

c = 500 miles apart

50 miles of course because north and west are next to each other so you calculate what is between the measurements.

Don't forget to account for length contraction if you're in a moving reference frame ;-)
