### Step-by-Step Solution: 1. **Understanding Speed**: Speed is defined as the distance traveled by an object per unit of time. The formula for speed (v) can be expressed as: \[ v = \frac{\text{distance}}{\text{time}} \] 2. **Distance**: Distance is a scalar quantity, which means it only has magnitude and no direction. By definition, distance cannot be negative. For example, if an object moves from point A to point B, the distance covered is always a non-negative value. ...
