Question
On her bicycle ride Fabiana's position (in $\mathrm{km}$ ) as a function of time (in hours) is $s(t)=22 t+17$. What was her average velocity between $t=2$ and $t=3$ ? What was her instantaneous velocity at $t=2.5 ?$
Step 1
The average velocity is calculated by the change in displacement over the change in time. The displacement is given by the function $s(t)$, so we need to find $s(3)$ and $s(2)$. Show more…
