The answer would be A:
You would use distance=rate•time to solve:
450 • 2.5 = 1125
350• 2.5 = 875
Since plane A is going west and B is going south, they form a right triangle, so you can use the Pythagorean theorem to solve for the distance between them, which we will represent as x:
1125² + 875² = x²
1265625 + 765265 = x²
2030890 = x²
Once you square root x, it's about 1425.09298, which is closest to answer A, 1425.0
