Which scenario best illustrates velocity rather than speed?

Explanation:
Velocity is speed with a direction. The plane example gives both how fast and a definite direction (heading 90 degrees), so you can describe its velocity as moving in that specific direction. The car example only states speed, with no direction. The cyclist’s path involves turning, so there isn’t a single fixed direction to describe a single velocity vector. The train says it’s moving in a straight line, which implies a direction, but it doesn’t specify which direction; the plane’s explicit heading makes the velocity concept clear.
