Answer 2

Answer:

the rate at which somebody/something moves or travels

Step-by-step explanation:

✨Speed is a measure of how fast something is moving. The average speed of an object in a certain time is the distance the object travelled divided by the time.

✨ Speed is also the distance covered by an object per unit time.

✨An example of speed is someone cleaning a room in 10 minutes.

✨Speed and velocity are both measured using the same units.The SI unit of distance and displacement is the meter.

✨The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second.
