Speed is a scalar quantity

Velocity is a vector quantity

Therefore, there are two components to velocity: the magnitude, or speed, and the direction of the motion.

Here's your example:

You are traveling at a constant speed of 100 miles per hour east on a highway. Since the velocity already includes the magnitude of the speed, the speed is also constant but has no direction.

Second one example: You are going around a circular track at a constant speed of 10 mi/hr. Since, it's a circular track, will the direction of your travel be the same? Therefore, in this case the magnitude of velocity which is speed is constant, but the velocity changes due to the change in direction.
