Questions: What two units of measurement describe speed? Distance and length Distance and time Average speed and distance Average speed and time

Solution Steps

Speed is defined as the rate at which an object covers distance. It is a scalar quantity that describes how fast an object is moving. The formula for speed is given by:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

From the formula, it is clear that speed involves two primary units of measurement: distance and time. Distance is typically measured in units such as meters, kilometers, or miles, while time is measured in seconds, minutes, or hours.

Given the options:

• Distance and length
• Distance and time
• Average speed and distance
• Average speed and time

The correct pair of units that describe speed are distance and time.
