So they have both been flying for 2 hours. The plane flying north is traveling at 150 mph so in 2 hours it has gone 300 miles. The plane flying west is traveling at 200 mph so after 2 hours, it has gone 400 miles. If you connect the endoints of the two planes it makes a right triangle. The distance between them is equal to the hypotenuse.
