Final answer:
Chariot races in ancient Rome involved four main teams and could be quite swift, but exact durations are not precisely recorded. They were dangerous events that could last several minutes, depending on the number of laps around a circus.
Step-by-step explanation:
The question regarding the duration of a chariot race scene is likely referring to a specific medium, such as a film or historical account. However, without a specific context, we can provide information on chariot races in ancient Rome. Chariot races were a major form of entertainment with races involving four teams represented by colors: Green, Red, Blue, and White. While the exact duration of these races isn't specified in the historical record, they were known to be swift and could be very dangerous for the charioteers. For instance, races could involve multiple laps around a circus, such as the Circus Maximus in Rome, which could make the event last several minutes.
