While reading about the history of different towns, Jared learned that Euston had 20 more carriages than Norfolk. Norwich had 100 carriages, and Flying Scotsman had 20 more carriages than Norwich. If Euston had 130 carriages, how many carriages are there in all? Let's be accurate as possible.
If Flying Scotsman had 20 more carriages than Norwich, and Norwich had 100 carriages, then Flying Scotsman had 100 + 20 = 120 carriages. Together, Flying Scotsman and Norwich had 120 + 100 = 220 carriages. If Euston had 130 carriages, 20 more carriages than Norfolk, Norfolk had 130 - 20 = 110 carriages. Together, Euston and Norfolk had 110 + 130 = 240 carriages. Altogether, Euston, Norfolk, Norwich, and Flying Scotsman had 240 + 220 = 460 carriages.
The answer: 460.
