These data show the splits every 10 meters for the top four finishers in the mens 100-m track final in the 1988 Olympics in Seoul, South Korea. Times are in seconds and hundredths, distance in meters. The times at distance "0" are the "reaction times" from the data we found on the web. We think they're the time from the gun until the runners started moving forwards. Or something like that.

This race is particularly notorious because Ben Johnson was originally awarded the gold, but was later disqualified.

Questions: roughly, how fast are the runners going? How fast is that in miles per hour? Do they accelerate through the entire race?
