Answer:
v = 0.33 [m/s]
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/physics/college/qp6ffabr2l0lvmj777o13m7w9myf8ku59c.png)
where:
v = velocity [m/s]
d = displacement = 40 [m]
t = 2 [min] = 120 [s]
Now replacing we have:
![v=40/120\\v=0.33[m/s]](https://img.qammunity.org/2021/formulas/physics/college/ck5ahgeprlvmo8evrkcfjp4a07j6uqly3g.png)
