Question

1. the speed you read on a speedometer is -----. constant speed instantaneous speed average speed velocity

Explanation:

To solve this, we analyze the definitions:

• Constant speed: Speed that doesn’t change over time (not what a speedometer shows at a moment).
• Instantaneous speed: The speed of an object at a specific instant in time. A speedometer displays the speed at the exact moment you look at it, so this matches.
• Average speed: Total distance divided by total time (calculated over a period, not shown on a speedometer).
• Velocity: Speed with direction (speedometer shows only speed, not direction).

Answer:

B. instantaneous speed (assuming the options are labeled with the purple box as B; if labels differ, the correct option is the one with "instantaneous speed").
