Answer:
The average velocity is [tex]v_{average}=25[/tex].
Explanation:
The average velocity is calculated in the following way:
If [tex]s(t)[/tex] represents the position of an object at time [tex]t[/tex],
and [tex]s(t_{1})=a[/tex] ; [tex]s(t_{2})=b[/tex], the average velocity is defined in that interval as:
[tex]v_{average}= \frac{final.position-initial.position}{elapsed.time}=\frac{b-a}{t_{2}-t_{1}}[/tex]
Taking the data from the question:
[tex]v_{average}=\frac{173-123}{3-1}=\frac{50}{2}=25[/tex].
