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) 33 200 72 400 119 600 171 800 227 1000 297 1200 372 1400 449 1600 (a) What was the man's average speed (rate) between 72 s and 171 s? (Round your answer to two decimal places.) m/s (b) What was the man's average speed between 297 s and 449 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?
