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.

Time (s)	Distance (m)
34	200
74	400
118	600
163	800
210	1000
287	1200
365	1400
444	1600

(a) What was the man's average speed (rate) between 74 s and 163 s? (Round your answer to two decimal places.) m/s (b) What was the man's average speed between 287 s and 444 s? (Round your answer to two decimal places.) m/s (c) Calculate the man's speed for each lap. Is he slowing down, speeding up, or neither? slowing down
