Answer 1

Part A: The athlete ran the 100 meter sprint in 13.2 seconds.

Part B: To arrive at this answer, I followed the rule for rounding decimals. Since the digit immediately after the tenths place (the hundredths place) is 4 or less, I rounded down the tenths place to 1. Therefore, the time is rounded to 13.2 seconds.
