Answer:
d = - 10 [m]
Step-by-step explanation:
We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.
![v = d/t](https://img.qammunity.org/2021/formulas/mathematics/middle-school/amfnhpcqkq148uhhv5ruclbkh4h1cjk1c3.png)
where:
v = velocity = 2 [m/s]
d = displacement [m]
t = time = 5 [s]
Now replacing:
![d=-5*2\\d=-10[m]](https://img.qammunity.org/2021/formulas/physics/high-school/xdbvzamuatvfn4f39eyu3s6fuxuvmnxtpe.png)
