Answer
The second fastest time Ben Johnson ever ran was 9.8 seconds. This was at the 1988 Summer Olympics in Seoul, South Korea. Johnson won the gold medal in the 100 meters race, but was later disqualified after it was discovered that he had taken steroids. The time of 9.8 seconds is still the second fastest time ever recorded, behind Usain Bolt's world record of 9.58 seconds.
