Question

4. If a runner completed a 100 meter dash with a time of 13.75 seconds what is the runners speed? Velocity?

Answer 1

Speed is given by Distance/ Time taken

$\begin{gathered} \text{speed =}\frac{Dis\tan ce}{Time\text{ }}\text{ =}\frac{100\text{ m}}{13.75\text{ s}} \\ \text{Speed = 7.27m/s } \end{gathered}$

The Velocity is 7.27m/s in the direction of the runner
