When an object covers equal distances in equal amounts of time, it is moving at a constant speed.

Here's why:

* Speed is a measure of how fast an object is moving.

* Constant speed means the object is moving at the same rate throughout its journey.

* If the object covers the same distance in the same amount of time repeatedly, it indicates that its speed is not changing, hence constant.
