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) 52 200 108 400 165 600 223 800 285 1000 352 1200 423 1400 497 1600 (a) What was the man's average speed (rate) between 108 s and 223 s? (Round your answer to two decimal places.) m/s (b) What was the man's average speed between 352 s and 497 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? O slowing down O speeding up O neither
