Hello how may I help you? Hi! I need to know facts about world records. Sure, which world records? Can you tell me who is the fastest Olympic track sprinter? Usain Bolt is the fastest Olympic sprinter What was his fastest time on 100m dash? He holds the world record at 9.58 seconds, a blistering pace! Wow. It's good to know. Any other records you want to know about? I think that's all. Thanks! Take care!
