PLEASE HELP! LAST DAY TO TURN IN AND IM SO BEHIND!!!

Answer
option C) velocity
Explanation
acceleration = Δv ÷ Δt
Answer
option C) m/s²
Explanation

= m/s ÷ s
= m/s x 1/s
= m/s²
Answer
option B) velocity has both direction and speed.
That is why velocity can be negative but speed can not and velocity is rate of change of displacement where as speed is rate of change of distance.
