If the speed of an object is unchanging, then what must be true?

the object is traveling at an average speed.

the object is traveling at a constant speed.

the object is traveling at a decreasing velocity.

the object is traveling at an increasing velocity

If the speed of an object is unchanging it means that it's traveling at a constant speed.

If the speed of the object increases or decreases it means that the speed is changing. That's why those options are not valid.

The average speed implies that the speed changes over time, but just the average remains the same. That's why this option is not valid.

If the speed of an object is unchanging, then the object is traveling at a constant speed.

"Unchanging" and "constant" mean the same thing.
