A minus sign attached to an average velocity indicates something about its:
APrecision
BDirection
CMagnitude
DDuration
Answer & Solution
Correct answer: B. Direction
1. Velocity is a vector, so the sign carries meaning.
2. An average velocity is computed as displacement over time.
3. In the worked example the minus sign indicates a direction.
4. It shows the average velocity is toward the rear of the plane.
