Relative Velocity: a Plane Flies Directly Between Two Cities, a and B

question 48

Multiple Choice

Relative velocity: A plane flies directly between two cities, A and B, which are separated by 2300 mi. From A to B, the plane flies into a 65 mi/h headwind. On the return trip from B to A, the wind velocity is unchanged. The trip from B to A takes less than the trip from A to B. What is the airspeed of the plane, assuming it is the same in both directions?

• A) 530 mi/h
• B) 400 mi/h
• C) 480 mi/h
• D) 610 mi/h
