Question

From the list of world record track events in the table, calculate the average speeds for each race. Assume the length of each event is known to the nearest 0.1 m.

Answer 1

`\begin{equation*} 9.5\text{ m/s} \end{equation*}`

Step-by-step explanation

We want to calculate the average speed for the 100 meters race.

To do this, divide the distance traveled in the race by the time taken to complete the race:

`\begin{gathered} s=(100)/(10.49) \\ \\ s=9.5\text{ m/s} \end{gathered}`

That is the average speed for the 100 meters race.
