This sounds like a homework question to me.
And my answer is... please do your own homework. Cut and paste other people's answer is not going to help you learn anything and it is also called plagiarism.

Speed is the magnitude of velocity. That is, it tells how much velocity we have, but not where we're headed.
Velocity has both magnitude AND direction. The magnitude of velocity is speed. Velocity tells us which way we're headed, and how fast.
Acceleration is just a change in velocity. This means that if we change our speed, we accelerate. It also means if we change our direction (but not necessarily our speed) we accelerate.
Example - When you're in a car turning a corner, your body tries to lean into the door, even though you're rounding the corner at about the same speed!! This is because you're changing the direction in which you're traveling; hence, you experience a force!
*EDIT* Sorry Tiger_Track, you're WAY off!!!!

Tiger_track, that's shocking!!
One thing you need to know is that both acceleration(dv/dt) and velocity(ds/dt) are vectors while speed is a magnitude.
both speed and velocity have SI units of m/s. and acceleration has SI unit of m/s^2.
Speed is simply =distance traveled/time while v and a are fairly complicated depending on the problem.

Speed = Distance / Time; Unit = m/s
Velocity = Speed / Time; Unit = m/s^2
Acceleration = Velocity / Time; Unit = m/s^3
