Answer 1

Answer:

  465.988 mph

Step-by-step explanation:

The two speed vectors form two sides of a triangle. Their included angle is 45°, so the law of cosines can be used to find the resultant magnitude x.

  x^2 = 500^2 +50^2 -2·500·50·cos(45°) ≈ 217,144.66

  x ≈ √217,144.66 ≈ 465.988 . . . . miles per hour
