Question
An airplane maintains a heading due east with an airspeed of 200 km/h. A wind blows from the north at 50 km/h. The direction of the plane's velocity relative to the ground will be
Correct Answer
Option C is the correct answer.
Detailed Explanation
The plane's velocity relative to the ground is the vector sum of its velocity relative to the air (200 km/h east) and the wind's velocity relative to the ground (50 km/h south). The resultant vector will point somewhere between east and south, i.e., south of east.
Hint
Draw the vectors: one pointing east (plane's heading) and one pointing south (wind). The resultant diagonal will point into which quadrant?
