When an object moves at the same speed and its direction doess not change, it moves with velocity

constant

Explanation:

velocity is a vector. it has value and direction. if the value and direction remain same from the start to the end it's call rectrilinear motion which have constant velocity

note: speed is scalar or have a value or magnitude only, without direction

speed = distance/time

velocity = displacement/time
