Explanation:
1) Position of first airplane after 2.4 h
Constant velocity ⇒ V = d / t ⇒ d = Vt =
d = 750m/h × 2.4h = 1,800 m; 51.3°
2) Position of the second airplaine after 2.4 h
Constant velocity ⇒d = 620m/h × 2.4 h = 1,488 m; 163°
3) Angle between the airplains, α:
α = 163° - 51.3° = 111.7°
4) Cosine theorem
a² = b² + c² - 2bc cosine (α)
b = 1,800 m (calcualted in part 1)
c = 1,488m (calculated in part 2)
α = 111.7°
⇒ a² = (1,800m)² + (1,488m)² - 2(1,800m)(1,488m) cos(111.7°) = 7,434,803 m²
⇒ a = √(7,434,803 m²) = 2,726.7 m ≈ 2,727m
a is the distance that separate the two airplains after 2.4 h
