How fast a car goes is known as its
a. velocity
b. speed

i am a little confused

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.
