Speed is defined as which of the following?

• A. The rate of motion in a given direction.
• B. The total distance traveled over a time interval.
• C. The distance an object moves in a given time.
• D. The energy required to move the object.

Answer: (C)

Speed is how fast something moves, meaning the distance it covers in a given amount of time. The option that talks about the distance an object moves during a specific time interval expresses that distance per that time, which is exactly the rate of motion. For example, if a car travels 60 kilometers in 1 hour, its speed is 60 km per hour. The other ideas describe direction (velocity), just distance, or energy, which aren’t speed.
