Question

A man is inside an airplane and walking toward the back of the plane at 7 m/s. The plane is flying West at 245 m/s. What is the speed and direction of the plane relative to the man?

7 m/s East

238 m/s, East

252 m/s West

238 m/s, West

Answer 1

7 m/s East

Step-by-step explanation:

The speed of the man relative to the plane is given as 7 m/s. Given that he's walking in the corridor of the plane, this is his speed relative to the plane. Since he's moving to the back of the plane, and the aircraft is headed to west, the man's direction relative to the plane is East.
