A Man Is Running Around a Circular Track That Is

Short Answer

A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runner's time at the end of each lap, obtaining the data in the following table.
What was the man's average speed (rate) between 68 s and 203 s? Round the answer to two decimal places.
$$\begin{array} { | c | c | } \hline \text { Time (s) } & \begin{array} { c } \text { Distance } \\( \mathrm { m } )\end{array} \\\hline 32 & 200 \\\hline 68 & 400 \\\hline 108 & 600 \\\hline 152 & 800 \\\hline 203 & 1000 \\\hline 263 & 1200 \\\hline 335 & 1400 \\\hline 412 & 1600 \\\hline\end{array}$$
