there are two planes. they both leave the airport at 1pm. one plane travels north at 150mph and the other plane travels west at 200mph. how many miles will they be apart at 3pm?

One plane will be 300 miles away; the other will be 400 miles away.
Consider this a right triangle and use the Pythagorean theorem to find the hypotenuse.
