Answers:
(a) 429.26 mi N and 2434.44 mi W; (b) 280°
Step-by-step explanation:
A compass bearing of 100° (E by S) is 10° south of 90°.
The jet is flying the hypotenuse of a right triangle.
(a) Distances from Miami
sin10 = OM/2472
OM = 2472sin10 = 2472 × 0.173 648 = 429.26 mi
OR = 2472cos10 = 2472 ×0.984 8077 = 2434.44 mi
Reno is 2434.44 mi west and 429.26 mi north of Miami
(b) Return bearing
Bearing = 100 + 180 = 280°
For the return flight, the jet should fly a bearing of 280° (W by N).

The distance to the west is 2434.44 miles, and the distance to the north is 482.57 miles. In turn, on the return the plane must travel to a bearing of 180°.
Given that a jet leaves Reno, Nevada and is headed toward Miami, Florida at a bearing of 100 °, and the distance between the two cities is approximately 2472 miles, to determine (A) how far north and how far west is Reno relative to Miami; and B) if the jet is to return directly to Reno from Miami, at what bearing should it travel; The following calculations must be performed, applying trigonometric and Pythagorean functions:
- Sen 100 = Distance west / 2472
- West distance = 2472 x sin 100
- West distance = 2472 x 0.9848
- West distance = 2434.44
- 2424.44² + X² = 2472²
- 5,877,909.3136 + X² = 6,110,784
- X² = 6,110,784 - 5,877,909.3136
- X = √232,874.6864
- X = 482.57 = North distance
- 280 - 100 = 180
Therefore, the distance to the west is 2434.44 miles, and the distance to the north is 482.57 miles. In turn, on the return the plane must travel to a bearing of 180°.
