Question: If a plane is flying at 200 km/h and the wind is blowing at 50 km/h in the opposite direction, what is the plane\'s speed relative to the ground?
Options:
Correct Answer: 150 km/h
Solution:
The plane\'s speed relative to the ground is the speed of the plane minus the speed of the wind: 200 km/h - 50 km/h = 150 km/h.
