Step-by-step explanation:
Formula:
![velocity = (d / t)](https://img.qammunity.org/2023/formulas/physics/college/z7ejg0pt9cfib48wy245ce7h3sn9srxqap.png)
d = distance given
t = the amount of time given
Substitute the given values into the formula for velocity:
![v = 8 / 4](https://img.qammunity.org/2023/formulas/physics/college/eg8j039hode3scher65wmrcfj1f011nf7y.png)
velocity is shortened for v.
8 (distance) divided by 4 (time) equals the velocity.
Solve:
![2 = 8 / 4](https://img.qammunity.org/2023/formulas/physics/college/zeo0z908e8bk3548on9zt2j8ehnz6xv02v.png)
The velocity of the toy car equals: B. 2 m/s.
