Felicity and her friend Nigella depart Felicity’s family’s thirty-two-room summer house in order to meet Giles and Trevor for high tea at the Chancery Buttery near Vauxhall Mews. Their chauffeured Bentley will traverse the twenty-seven kilometres at an average rate of 47.3 kilometres per hour. At kilometre two the following exchange takes place:

Felicity: “That hat is so last season. Did your mum fob it off on you?”

Nigella: “No, dear, it’s Harrod’s Fourth Floor, actually. You won’t find this design at that dreary milliner’s on the mezzanine. Oh, I’m sorry! You shop there, do you not?”

Question: What distance does the Bentley travel during the 18 minutes of silence that ensue?
