Answer:
See the explanation below.
Step-by-step explanation:
The units of work are consistent since if we work in the international system of measures we have the following dimensional quantities for velocity, distance and time.
s = displacement [m]
v and u = velocity [m/s]
t = time [s]
Now using these units in the given equation.
![s = 0.5*([m/s]+[m/s])*[s]\\s=0.5*[m/s]*[s]\\s = 0.5*[m]](https://img.qammunity.org/2022/formulas/physics/high-school/kxnkxyqc5mji8zgxz1vumpjj3kuo2ryynh.png)
So the expression is good, and dimensional has consistency.
