How long is the ticket valid?
'Dura' — DU-ra. Short 'u'; this is the third person singular of 'durare' (to last/to be valid for).
Ask at the ticket window or machine before buying. Different tickets have different validity windows — a BIT in Rome lasts 100 minutes for surface transport after validation.
'Durare' means to last in time. 'Quanto dura?' is therefore how long does it last? — a concise and natural question. The ticket 'dura 100 minuti' (lasts 100 minutes). Note: on the metro in Rome, the BIT covers one metro journey regardless of the 100-minute window.

Rome's BIT (Biglietto Integrato a Tempo) is 100 minutes and covers unlimited bus and tram journeys but only one metro entry. The 48-hour and 72-hour tourist passes offer better value for visitors using multiple journeys.
