How fast a car goes is known as its speed.

Speed = (distance covered) divided by (time to cover the distance)

It has nothing to do with the direction the car is going.
______________________________________

The car's velocity is its speed AND the direction it's going.

30 miles per hour . . . speed

40 miles per hour north . . . velocity

20 miles per hour south
20 miles per hour west . . . . . same speed, different velocity

-- 'Velocity' is NOT a big word that you use when you mean
'speed' but you want to sound smarter.  It's a different thing.

-- If you don't know anything about the direction the car is going,
then you can't say anything about its velocity.

-- If the car is going around a curve, then its velocity is constantly
changing, even if its speed is constant.
