Meters per second is a measure of:

  1. Distance

  2. Time

  3. Acceleration

  4. Speed

The correct answer is: Speed

Meters per second is a unit of measurement that specifically describes the rate at which an object moves, essentially indicating how many meters an object travels in one second. This quantifies speed, providing both a value and a directional aspect when combined with vector information, making it a fundamental measurement in physics and various applications involving motion. Speed is defined as the distance covered per unit of time, and because meters and seconds are the standard SI (International System of Units) measurements for distance and time, respectively, this unit directly illustrates that relationship. In contrast, distance measures how far an object has moved, time measures the duration of an event, and acceleration describes the rate of change of velocity over time. Therefore, meters per second distinctly aligns with the concept of speed.
