Solving for Displacement when Average Velocity and Time are Known

Layla jogs with an average velocity of 2.4 m/s east. What is her displacement after 46 seconds?

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Strategy
We know that Layla's average velocity is 2.4 m/s east, and the time interval is 46 seconds. We can rearrange the average velocity formula to solve for the displacement.
Solution
$\begin{matrix} v_{avg} & = & \frac{Δ d}{Δ t} \\ Δ d & = & v_{a v g} Δ t \\ = & (2.4 m/s)(46 s) \\ = & 1.1 \times 10^{2} m east \end{matrix}$
